PRESTRESSING (POST TENSIONED) CONCRETE ‘SOFTWARE’ DESIGN WORKSHOP12.30 – 1.30 LUNCH - (Provided at Venue)

1.30 – 3.00 SESSION 3 PT Industrial Slabs on Ground

Designing industrial slabs on ground is a specialised PT area therefore this session will address the formulas and methods associated with stressing slabs on the ground.

It will address soil friction values, the various applied loads, general restraints, total loss of prestress and how to measure this on site.

The session will then use a new program called PTsog to speed up the process of design but again provide simple and useful graphical images to allow the designer to understand what is happening during the design process.

3.00 – 3.30 Afternoon Tea

3.30 – 5.00 SESSION 4 PT Tanks

This session will address all the formulas associated with stressing a post tensioned tank (either in situ design or precast design). The design of tanks is quite a complex process so engineers really need to understand PT in order to design correctly. This is why the presenter will be very thorough in his explanation of all the steps and reasons for making certain choices before embarking on the full design

The session will then use a powerful (but user friendly) program called PTtank to speed up the process of design. This program calculates the effects of liquid pressure, temperature effects, earthquake, soil pressure etc. it then provides the designer with the size of tendons and spacing both vertically and horizontally in the walls (and floors).

5.00 – 5.15 Feedback Sheets & Certificates of Attendance

THE WORKSHOPThis new PT software workshop will allow structural/civil engineers to design PT structures quickly whilst still understanding the processes involved via a more interactive input of data and output of results.

Some software programs today have become so sophisticated that the design engineer has no real feel for the processes carried out by the program and thus has to rely on the correctness of its output.

For this reason CCS is introducing this new course which will be a logical follow on from the standard two day Prestressed Concrete Design Workshop that CCS has conducted over the past 10 years.

The course will be broken up into specific sessions addressing various areas of prestressed concrete (ie primarily post tensioning) .

Each attendee will be issued with a dongle on the day with the programs to be used in the workshop. Please note that these programs will be deactivated at the end of the course.

However if attendees are interested in purchasing the relatively inexpensive programs for their office this can be discussed with the presenter.

PROGRAMME8.30 – 9.00 Registration

9.00 – 9.10 INTRODUCTION

9.10 – 10.30 SESSION 1 General PT Design

This session will start with basics of prestressing and the formulas upon which the design is based.

The presenter will outline the materials used (eg 12.7 mm vs 15.2 mm PT strand), grades of concrete chosen for PT specifically, Australian Standards requirements for design and so on.

Much of this information will be referenced from the HELP section of the various PT programs available from this speaker eg PROFILE.

10.30 – 11.00 Morning Tea

11.00 – 12.30 SESSION 2 Suspended PT Slabs and Beams

Once the attendees have had a refresher in PT design, then the presenter will explain the basics of designing PT beams and suspended slabs in buildings.

He will then use an efficient but simple program called EFNG to speed up the design process. This program allows the designer the ability to size up beams and slabs and the necessary tendons and reinforcement requirements to satisfy the applied loads, minimum P/A requirements minimum radius of curvature for tendons and so on for a PT system.

Clear graphical outputs gives the designer a step by step understanding of the processes carried out by the program. The program also does a final estimation of the quantities of materials required to allow for a more accurate costing estimation.

SPEAKERSteven S. Gikas BE MEngSc MIE(Aust) NPER Director - Steven S. Gikas & Associates

Steven Gikas has been designing post tensioned structures including PT liquid retaining structures for over 25 years. He was the Senior Design Engineer for VSL from 1985 to 1996 before starting his own consulting firm specialising in this area. Steven has written the PTtank program based upon his many years of design experience in PT. He has also written PT slab on ground programs as well as programs that design for Punching Shear in Reinforced and PT structures as well as programs that take quantities off drawings.
