What’s New in Orion Release 15.1sp4

2 October 2009

1 What’s New in 15.1 sp4 General As a rule the intention of an Orion service pack is primarily to address critical issues that have come to light since the previous release. In addition to providing the above in 15.1 sp4, we have also taken the opportunity to launch a significant new feature along with other more minor enhancements. Because of its potential benefits, the major new feature being introduced is a "SPARSE SOLVER" option.

NEW Sparse Solver The purpose of the sparse solver is to reduce the time required for analysis during the building analysis process. For certain model types a dramatic reduction in the analysis time can be achieved, for other models it may be less significant. Activation of the sparse solver is optional, it is located on the Model Options/Settings tab as shown below:

Also located on this tab is a new option enabling you to switch off the creation of a detailed analysis echo file. In previous releases the detailed analysis echo file and the model export files were always being created whether you required them or not. Now you can choose if you require them or not. Notes:

1. Switching off the detailed analysis echo file creation speeds up analysis whether the sparse solver is used or not.


3 October 2009

2. Understanding the Analysis Process: Before discussing the solver speed increase it is important to have a brief appreciation of the stages that occur when an analysis is requested in a product such as Orion. This can be thought of as a 3 stage process:

• Analysis model creation In this stage the 3D model data is used together with all the analysis model preferences you have defined (e.g. meshed walls or mid-pier walls) in order to create and load the analysis model. Things like the automatic pattern loading are also determined in this phase.

• Analysis The stage in which actual analysis happens and in which the sparse solver speed increase applies.

• Solution data handling When the analysis is complete the results have to be saved into the main model database where they can be accessed for member design.

3. Solver speed increase: As is noted above, the sparse solver option will reduce the amount of time spent in the second stage. The percentage gain is not linear, the bigger the model the bigger the gain tends to be. The gain tends to be particularly impressive when walls are meshed. For example, in a model which previously took 11 minutes in the analysis phase the sparse solver now takes just 30 seconds. In terms of the overall analysis process the total time taken for this example was 15 minutes (stages 1 and 3 accounting for 4 minutes), and this reduces to 4mins 30 secs.

4. Really big models that could not be solved at all in the old solver can be solved when the sparse solution is used.

5. For all models that solve in the old solver the sparse solver has been shown to give identical results.

6. Models that contain mechanisms (too many pins!) will not solve at all in the sparse solver - you are informed that an error has been encountered. In such situations you can swap back to the non-sparse option which will solve, (but with warning messages about singularities) - you should then proceed to sort out the mechanisms. It is primarily for this reason that the two solver options are being retained in the new release.

Note: We advise against indiscriminate pinning and recommend that if you have analysis messages about instability the best way to proceed is to make a copy of the model and remove all pins - if the analysis then runs successfully you should re-consider the extent of the pins introduced previously.

We consider that a key feature of Orion is the wall modelling sophistication and the fact that two analytical idealisations are supported. Many customers like the confidence that is introduced by being able to make a cross check between these options. In practice however, the meshed wall option often became impractical for large models. The new sparse option means that meshed walls can be used on many more models. For more detailed discussion of the wall modelling idealisations refer to chapter 3 of the Orion Engineer’s handbook and the training presentation that this links to. A technical note “Shear Wall Analysis – New Modelling, Same Answers” published in the Institution of Structural Engineers Magazine and on which the Orion modelling is based, can be accessed at: http://services.cscworld.com/techpaper.php

NEW Analysis Model Export Options

Further model export options have been provided on a new Model Export tab as shown above.

Other Fixes and Enhancements General Program Operation • The issue where the Delete Key worked inconsistently has been resolved, the delete

operation can now always be activated this way. • A number of minor issues causing program instability have been isolated and fixed.

Foundation Design The conservatism that arose due to imposed load reductions not being considered in foundation design has been removed.

Column Schedule A longstanding limitation that a maximum of 20 storeys could be scheduled at one time has been removed.

Beam Detailing A number of issues have been addressed, including: • A 'Missing' hogging reinforcement dimension on one side of internal supports has been

reinstated. • If link labels are positioned inside the beam, the link zone dimensions are now also positioned

inside the beam. • Beam Size parentheses reinstated in beam label. • A new option is introduced to allow end anchorage lengths (into shear walls for example) to

be extended beyond basic code requirements. • A number of cases where the beam detail drawing could not be created at all have been dealt

with, there are no known outstanding examples of this type of issue.


5 October 2009

3D Model Viewer A number of changes have been made to the new 3D viewer which was first introduced in R15.1, this includes improvements to: • Improved Mouse wheel sensitivity when zooming. • Slab transparency adjustments • Cases where parts of the model were not shown depending on zoom. • Grey background for new models.

Automatic Beam Load Determination Issues with the Yield Line load decomposition have been resolved: • Two yield line loading decomposition problems that caused loss of load in 15.1 sp3. • A more common situation where the beam load was too high resulting in some local over

design has been fixed. • Note that customers affected by these issues were alerted by inconstancies in the axial load

comparison report and switched to the use of “FE load decomposition” to avoid the issue.

Additional Feature Highlights In this section some features which have been recently introduced but not previously highlighted are noted.

The option to insert multiple parallel beams Press the ‘Shift’ key when creating a beam and a dialog will appear to allow a series of offset beams to be defined. A preview of the offset beam locations (as shown below) assists in this process.

‘Shift’ Dialog for Offset, Multiple (and Curved) Beam Definition


6 October 2009

Graphical highlighting of elements when selecting This feature is designed to help working with large models. • With the Selection tool active, moving the cursor over the plan view causes the element under

the cursor to be highlighted. This makes it easier to make selections without having to zoom closely into the area.

Element highlight (and tooltip) assists the selection process.

Remember that members can be selected in any of 3 ways: • From the Main Plan View

• From the 3D View


7 October 2009

• From the Tree View

• And the right click menu gives access to all forms of data and results for the selected

member(s).

Converting rib & waffle slabs to beams Once a rib or waffle (grillage) slab has been defined, a command exists on the right click menu to convert the ribs into beams. This could be useful in cases where you are seeking an accurate design of each independent rib element. For example if significant point loads exist. Convert Ribs to Beam Elements option


8 October 2009

Applying filters to the 3D view Various filters can be applied to the 3D view to facilitate the editing of complex models in 3D. Multiple filters can be applied simultaneously by selecting Storey and Member Type Filters. This activates the Filters dialog shown below.

Alternatively, filters can be applied which relate to the currently selected elements. These filtering options are summarised in the table below:

Filter by Axis Provided only axes are currently selected, this filter displays only those beams, columns and walls defined by the selected axes.

Display All Axes Switches off ‘Filter by Axis’.

Filter by Member Type Provided only one member type is currently selected, this filter displays all elements of that member type.

Display All Member Types Switches off ‘Filter by Member Type’.

Filter by Member’s Storey Displays only those members on the same storey as the selected member.

Display All Storeys Switches off ‘Filter by Member’s Storey’.

Filter by Member Axis Displays only those members that share a common axis with the selected member.

Display Only Current Storey Displays the current storey, maintaining any other filtering options.

Display All Members Switches off all filters.

Hide All Members Displays axes only.

What’s New in Orion Release 15.1

9 October 2009

2 What’s New in 15.1 General Orion R15.1 is a significant upgrade with many completely new features and numerous enhancements. One of the main themes of this release has been the expansion of Orion’s modelling capabilities to facilitate the input of more complex geometries. You will find the scope of the foundation design has also been significantly increased. CSC and the Orion team are committed to continually provide our users with high quality, market leading solutions for building structures.

NEW Inclined Member Modelling and Design It is now possible to model, analyse and design a wide range of inclined members including ramps, sloping beams, columns, walls (with tapers), split levels, stair and landing beams etc. Inclined Members

A new Plane definition feature makes creating inclined planes within the structure straightforward. Inclined Plane Definition

For further details about this new feature refer to Modelling Inclined and Lowered Members in Chapter 2 of the Engineer’s Handbook.


10 October 2009

NEW Curved Members Orion R15.1 introduces curved axes, beams and slabs. Curved Members

Axis definition and beam definition have both been enhanced. Press the ‘Shift’ key when creating an axis or beam and a dialog will appear to allow a curve to be defined. This dialog also makes it easy to create a series of offset axes or beams. ‘Shift’ Dialog for Offset, Curved and Multiple Beam Definition

For further details about this new feature refer to Modelling Curved Axes and Beams in Chapter 2 of the Engineer’s Handbook.


11 October 2009

NEW Pile Cap Design Orion 15.1 introduces pilecap design. Pile Cap Design Dialog

Pile Cap Detail

For further details about this new feature refer to Pile Caps in Chapter 21 of the Engineer’s Handbook.


12 October 2009

NEW Combined Foundation Design Combined Pad Footings and Pile Caps are now enabled. Combined Footing Detail

For further details about this new feature refer to Combining Columns and Walls for Shared Foundation Design in Chapter 21 of the Engineer’s Handbook.

NEW Model Linking for Common Foundation Design One or more additional models can be linked with the open model to allow a common foundation to be created for the entire project. The foundation loads are updated automatically if any of the linked projects are redesigned. Common Foundation under Linked Models

For further details about this new feature refer to Chapter 22 - Linking and Merging Projects in the Engineer’s Handbook.

13 October 2009

NEW Foundation Loads Table A new table which summarises the column and wall foundation forces determined from the building analysis is available. The table will also show the foundation forces from the members of any linked project. These values can be edited, and additional loads can be added if desired. Foundation Loads Table

When column and wall loads are shown on the plan view at foundation level, the edited or added loads defined in the above table are displayed. For further details about this new feature refer to The Foundation Forces Table in Chapter 21 of the Engineer’s Handbook.

NEW Eigenvalue Analysis An Eigenvalue Analysis can be performed during Building Analysis to calculate natural frequencies and mode shapes. The Eigenvalue Analysis results can then be used to assist with seismic design and can also be of value where information relating to wind tunnel tests is required. Modes Shapes in the Building Analysis Post-Processor

For further details about this new feature refer to Chapter 6 - Eigenvalue Analysis in the Engineer’s Handbook.

Enhanced Design Settings Additional checks are made to see that secondary effects arising from a 3D analysis are “ignorable”. Where the code gives no guidance on ignorable load thresholds the values are user defined. For other forces an automatic check is made based on the size of the section being used, for example: NEW Torsional Shear Check – The nominal torsional shear capacity of all sections are determined and checked against any torsion force that develops in the analysis model. Ignorable Forces in Beam Design Settings

Enhanced Detailing Five of the more significant detailing enhancements are listed below. In addition to these numerous other minor detailing enhancements and adjustments have been made.

1. NEW Angled Beam Linking Beams connecting at an angle can be automatically detailed as continuous on the detail sheet. If required the default linking can be adjusted by manually linking the angled axes. Angled Beams

Angled Beam Detail

For further details about this new feature refer to Linking Angled Beams in Chapter 2 of the Engineer’s Handbook.

2. Curved beam detailing Curved beams are detailed as if straight thus providing reasonable quantity estimations. Final details need to be checked and amended to account for the curve. Curved Beam Detail

3. Inclined member detailing Preliminary details are created which are again sufficient to provide reasonable quantity estimations. Final details need to be checked and amended to resolve details at angled intersections. Inclined Beam Detail


16 October 2009

4. Beam Detailing at “Pinned” Ends A new option added in beam design settings (as shown below) to make min top steel at pinned beam ends a user defined percentage. (Previously a fixed value of 50 % of the span steel requirements was used). The setting of the current/last project is used as default for new projects (including old projects for which this setting did not previously exist).

.

5. Link Provision in Columns A new option has been added to allow links to always be detailed through the full depth of all connected beams.

NEW Revit Structure Integration Links These are downloadable from the CSC website. For details go to www.cscworld.com/orion/tech.php

NEW 3D Window The 3D display window has been completely rewritten, providing a number of new functions:

• NEW 3D Design Status View option (Visual Pass/Fail status Display)

• Selections can now be made in the 3D window giving access to editing and design result interrogation.

• Improved Filtering

• Element Labelling

• Options to animate rotation an/or construction sequence.

• Record Video

New Look Icons throughout

Enhanced Documentation The Engineer's Handbook has been fully updated and re-organised to reflect all the significant new enhancements in this release. This document includes cross references to many of the new chapters. We would urge all Orion users to at least review the contents list of the latest handbook in order to appreciate the extent of help that is available.


18 October 2009

3 What’s New in 15.0 General Orion R15.0 is a significant upgrade with a large number of enhancements and many completely new features. A number of the changes introduced in this version are aimed at streamlining the analysis/design process. You will also find managing changes to the model much easier - a ‘traffic light’ system has been introduced for clarifying the current status of both the analysis and the design. CSC and the Orion team are committed to continually provide our users with high quality, market leading solutions for building structures.

NEW Batch FE Chasedown It is now possible to perform the FE analyses of every floor in your building at the click of a single button. All the required parameters can be predefined. No further user intervention is required unless you optionally choose to review the mesh at each level - to ensure it’s adequacy. Batch Chasedown Parameters

The batch FE chasedown can also be used without meshing for beam and slab models, when used in this way it can provide a much faster way of designing transfer beams for worst case loading.

NEW Analysis Status Clarification Orion R15.0 introduces intelligent model status tracking. On completion of the initial analysis and design run, the building design model is considered ‘up to date’. However given the dynamic nature of building projects it’s likely after the initial design there may be changes that need to be made to the model. On initiating changes to the model Orion R15.0 will invalidate appropriate analysis or design statuses and message the user on necessary steps that need to be taken to bring the model back up to date.


19 October 2009

This may involve re running the building analysis, repeating a F.E. floor load decomposition, or rechecking your beam design. At anytime you can clearly review the current status of the analysis and design. To achieve this a ‘traffic light’ system has been introduced to highlight those members for which the design result may be out of date. Storey Beam Design

Orion r15’s model status tracking will allow you to easily manage changes and keep on top of your projects. Design Status Window

Red Cross = Fail

Green Tick = Pass Amber Tick = Pass (based on previous analysis result)


20 October 2009

We hope that this in conjunction with the batch FE chasedown will mean that previous issues which arose when design was attempted based on old analysis results are avoided.

Column and Wall Design and Detailing Wall design has been significantly enhanced with the following reinforcing styles have been added: Option to use mesh reinforcement


21 October 2009

Option to consider a single layer of reinforcement

In addition, the following enhancements have also been introduced: Tie bars are now automatically omitted if the area of main steel is less than 2%.


22 October 2009

There is a new option to consider plain wall design (where wall is in compression throughout and steel requirement is zero/negligible, a reduced min % of steel is provided)

The format of the reinforcement quantities table on the application plan is changed and now includes bar marks and member referencing.

Note that the reinforcement application plan is immediately updated as columns are designed.


23 October 2009

You can shortcut to a details (elevated) view of any column/wall via the right click menu - make sure you have all the detailing options switched on in the column settings dialogue to see this best – as quite a few new options have been added. Column Steel Details New options to print the detailed design when designing interactively and also to see full design detail. Detailed Column Design Report


24 October 2009

Beam Detailing New Beam Detailing options have been introduced: New curtailment option to bend back bobs to avoid extending into columns

New option to set a tension lap factor – Common practice would be to adopt a factor of 1.4 as this would cover the vast majority (if not all) cases. Should you reduce the factor to 1.0 then it is your responsibility to increase the lap where necessary when detailing the beams.

Anchorage length of end bob bars is reduced in some cases where it was previously excessive.

Other items which are improved relating to detail presentation: Enhanced avoidance of overlapping text.

Better orientation of all types of dimensions resulting a clearer drawing.

Enhanced overlap control in the bars shown below the beam.


25 October 2009

Enhanced automatic merging of top and bottom bars with same size.

Enhanced visualisation of members at back and front of the beam.

Link zone dimensions added.

Enhanced beam sections are created.

Enhanced dividing of all bars when max cut length exceeded.


26 October 2009

Creation of detail drawings using the "All Axes to Single Sheet" option has been enhanced to allow separate sheets for each floor if required.

As previously, you can include a table of reinforcement quantities on each sheet created – but in release 15.0 this information can now also be placed in a report, or exported to either Excel or Access. The above two enhancements mean that you can quickly create all the sheets in a single run hence giving you the option to report quantities for the entire building or broken down on a floor by floor basis. You can still create drawing sheet arrangements manually by selecting/arranging beam lines – so in total you can report the quantities broken down in 3 different ways (note that bar marks will be different in each method).

User Interface Style Options have been added – These can be selected from the Graphical Editor Settings, General tab – these provide 4 options for toolbar style settings plus an option to have the properties dialog “fade” after specified time delay (set to 0 to avoid fading).

Re-ordering and re-naming of options in Run menu is clearer.

Definition of Material Properties has been moved from the Building Parameters dialog to the Building Analysis dialog.

New easier way to apply/edit column nodal loads

New option to display column design forces for any/every case/combination in plan view.

New option to display total added beam loads on each beam in plan view.


27 October 2009

Total Added Loads displayed on plan view

New options to print the column and beam design summary status lists. Summary Table Report for Beams


28 October 2009

Modelling There are numerous adjustments and enhancements making it easier to construct models. New "overwrite" option when generating members from one storey to another.

Foundation Depth setting is exposed and editable in the "Edit Storey" dialog.

New Slab Insertion by “Pick Points” is introduced.

When selected you pick axis intersection points to define the perimeter of the slab.

As soon as you click an intersection where a grid is found that goes back to the start point the slab is inserted. Therefore, for simple boundaries this option requires one less click per slab than the “Pick Axis” option.

Slab insertion by "Beam Region" is enhanced as follows:

If you click within a region that is not totally enclosed by beams, the program will attempt to detect an “Axis Region” instead - if found, a slab will be inserted within the axis region.

If you click within a region whilst pressing the CTRL key, “Axis Region” is automatically assumed - you can pick more than one axis region and the slab is inserted when CTRL is released. (i.e. Slab is not inserted to “Beam Region” if CTRL is pressed so this changes the insertion method to “Axis Region” on the fly).

Slab Insertion by “Pick Axis” is changed as follows:

When "Pick Axis" is first selected the axis list will be cleared so that you can immediately start picking axes. (i.e. it no longer goes into an editing mode).

At this point you can close the slab insertion dialog and continue with repeating steps below to insert as many slabs as you want.

You can then start picking axes sequentially (no need to press the control key).

If/when you click the first axis for a second time a slab panel will immediately be inserted (if valid) and the axis list will again be cleared so that insertion of the next panel can begin.

(Optionally, if you have kept the slab insertion dialog open you can insert the slab by clicking on "New Slab Panel" rather than re-clicking on the first axis as noted above.)

Enhancements to Beam Insertion Methods:

Inserting beams that overlap other beams - a new question is asked about whether you want the beams split to become secondary beams.


29 October 2009

New option to insert an offset beam - press the shift key while inserting a beam and a new dialog appears to input the offset distance (a slightly hidden feature).

Load Decomposition by FE Navigation between floors is now possible from the dialog

Automatic prompting to apply FE decomposed loads when the feature is used.

Automatic warning at start of building analysis if FE decomposed loads are to be used but the FE decomposition is not up to date.

Building Analysis Building analysis can be quite a bit faster for larger models.

Axial load comparison is enhanced to cope with case where “len-storey 2” columns which finish at the foundation level are used.

A completely new building Analysis Post Processor including:

Interface that is standardised with the FE floor post processor.

New "Find" feature Find Icon (circled)


30 October 2009

New Diaphragm Confirmation feature

FE Analysis If a column has a del z applied to raise the base level - this is now recognised in the FE model.

New options to "copy" graphics to windows clipboard implemented in FE and BA Post-processors. Can then "paste" into other applications.

FE Post-processor - Option to filter and show contours for specific slab depths.


31 October 2009

Punching Shear Improved routines for determining punching shear perimeters for more complex layouts.

New way of editing input data for punching shear checks (column editing in table). Column Editing Icon (circled)

Materials Export Quantity Extraction Reports have been significantly enhanced to allow reporting of reinforcement for all member types. Quantity tables can be exported to Microsoft Access or Excel.

Extract from Quantity Table for Beams


32 October 2009
