Unit of measurement The TS-Midas link allows the use of different units of measurement in the two softwares.

Environment management The link uses different sections & material databases, depending on the used Tekla Environment. These configurations are stored in the “MidasEnvironmentStandards.cnv” contained in the following folder:

C:\<Tekla Structures installation folder>\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

The typical paths are reported below:

C:\Program Files\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

C:\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

The content of “MidasEnvironmentStandards.cnv” is reported in the next page.

Section management In order to create a biunique correspondence between Tekla Structures and Midas Gen/Civil section databases, the link uses a mapping file named “MidasSectionMapping.cnv”. This file is contained in the following folder:

C:\<Tekla Structures installation folder>\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

The typical paths are reported below:

C:\Program Files\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

C:\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

A section of “MidasSectionMapping.cnv” file is reported below. The user can update/change the file.

TS name MIDAS name MIDAS DB name !UNI] UNI] !![Shape: L] L15*3 L15x3 UNI L20*3 L20x3 UNI L20*4 L20x4 UNI L25*3 L25x3 UNI L25*4 L25X4 UNI

NB: Some section mappings cannot be modified: e.g. Midas L-shaped profiles are converted in TS L-shaped

profiles if the material is steel (L profile with fillet radius), or in LC profiles (available in Tekla Warehouse) if

the material is concrete (L profile without fillet radius).

NB: If the link can’t find a mapped section name, the link tries to transfer a parametric section compiling

automatically the section parameters.

Twin profiles Actually, the export of twin profiles from TS to Midas is partially supported by the link (see “Cross section

data table”).

NB: To export Twin profiles, set “Consider twin profile” option to “Enabled” in “Analysis Model Properties”.

If the option is set to “Disabled” [default value] Tekla Structures exports Twin Profiles as two single elements.

The import of twin profiles in Tekla Structures is not supported.

Material management In order to create a biunique correspondence between Tekla Structures and Midas Gen/Civil material databases, the link uses a mapping file named “MidasMaterialMapping.cnv”. This file is contained in the following folder:

C:\<Tekla Structures installation folder> \<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

The typical paths are reported below:

C:\Program Files\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas

Two sections of “MidasMaterialMapping.cnv” file are reported in the next page. The first section is referred

to concrete, the second one to steel. The user can update/change the file.

Member axis location in the analysis model of Tekla Structures The TS-Midas link can handle the following options:

a. Neutral axis → The neutral axis is the analysis axis for all parts. The location of the analysis axis changes if the profile of the part changes.

b. Reference axis → The part reference line is the analysis axis for all parts. This option can’t be used if there are truss elements in TS model. If the user ticks the “Beam offset” checkbox in the export phase, the section offset is set in one of the 9 permitted reference axis positions (cyan grips in the below image) accordingly to the reference line of the part. If the user doesn’t tick “Beam offset” checkbox, the section offset is set in the centroid.

If “Neutral axis” is selected, the user should not check the “Beam offset” option during the export phase.

Export from Tekla Structures to Midas Gen/Civil 1) In “Analysis & design” tab click on “A&D models” 2) Click on “New” button

3) Choose the settings that best suit to your case. We suggest to use the creation method “By selected parts and loads” and/or use a filter that excludes all the secondary elements and connections.

4) Choose the correct Analysis application: “Midas 2017 – Rel.A” and eventually tick the “Set as default” option

5) Choose the proper Member axis location (for more details, please refer to “Member axis location in the analysis model of Tekla Structures” section)

9

6) Once clicked on “OK” button you should see the analysis model created according your settings. You can now check the correctness of the model. The user can modify the position of the analysis elements manually.

7) To export the analysis model, click the “Export” button

8) If there are no load combinations, the software will ask if you want to create load combinations. We suggest to answer “No” and create load combinations directly in Midas software.

9) By clicking on the OK button you’re declaring that the analysis model you’re exporting is in accordance with the physical model.

10) Choose the file format (Midas Gen or Midas Civil) and click on the “Continue” button

10

11) Select what needs to be managed by the link. By ticking “2D Elements”, the link will export the perimeter of planar elements, including also holes inside them – if holes are considered in the analysis model –. The perimeter is exported with peculiar elements characterized by

a. section number = 999999 b. section name = Contorno c. Profile: Round bar D=0.05mm

Please consider that the “2D Elements” tick will not affect panels whose Analysis member property class is equal to “Wall – Shear wall”. These panels are transferred in Midas as wall elements.

12) Once created the MGT/MCT file, the link informs the user that the process was completed.

13) You can find the MGT file in “<Model Folder>\Analysis\<Analysis model name>” folder.

11

Import/export of MGT files in Midas Gen/Civil In Midas Gen you can import the MGT file exported by Tekla Structures (click on the Midas Gen Icon → Import → midas Gen MGT file). In the following picture you can find the import process result. Beam elements are colored in white, wall elements in light blue and plate elements in pink. You can see that for planar elements with openings and planar elements with more than 4 nodes only the perimeter is transferred.

The user can easily select the perimeters and perform the mesh of the 2D elements.

12

In this example some changes are made in Midas Gen: a. A new floor is added b. The height of all the beams of the penultimate floor is increased from 600mm to 800mm c. The cross section of the column of the first two floors is increased from 400mm x 400mm

to 500mm x 500mm

To export the MGT file, click on the Midas Gen Icon → Export → midas Gen MGT file

13

Import in Tekla Structures of MGT file exported from Midas Gen/Civil 1) Overwrite the MGT file contained in the folder <Model Folder>\Analysis\<Analysis model name>

with the MGT file received from the Structural Engineer. 2) Open Tekla Structures and activate the CTRL+5 view mode 3) In “Analysis & design” tab click on “A&D models” 4) Click on the proper Analysis model name and click on “Import”

5) Choose the File format and click on “Continue” button

6) Select what the link should manage in the import process and click on “Continue” button. Please consider that 2D plate elements cannot be imported in Tekla Structures.

14

7) Once the link has finished analyzing the MGT/MCT file, you’ll see a window with info on “New members”, “Profile changes”, “Warnings”. Select the elements that you want to accept and click on “Accept selection” button. NB: Selecting an element in the “Profile changes” section will highlight the correspondent part in the model (see picture below).

8) After clicking on the “Accept selection” button you can close “Analysis & Design Model” window.

You’ll see that the model has updated the model with the latest accepted changes.

15

9) In order of looking at a glance what’s changed, a new representation filter has been created: “TS-Midas_status”. This filter works on the “TS-MIDAS_status” UDA:

• New items are colored in green

• Modified items are colored in yellow

• Deleted items are colored in red

• Items not changed in Midas are colored in grey (70% transparency).
