PRE-Stress | Design Software

PRE-Stress helps you analyze and run calculations on many types of prestressed concrete elements including hollow core slabs; slabs; beams; sloped beams and double tees. 

The software considers the whole life cycle of the prestressed element across all the production stages from the casting in the factory; de-tensioning; storage; transportation; lifting and handling; right through to the final placement in the building. Cracking occurring in the early stages of the element lives on throughout the calculation, affecting the calculations in the final stages. The program is based on a 2D FEM-engine for accurate numerical solutions and precise results.


Users of our IMPACT Design software can also benefit from the full integration of hollow-core calculations whilst detailing hollow-core floor layouts in 2D and now full 3D in the IMPACT Project Manager. Loads and supports defined in the model are sent to PRE-Stress along with section data, returning calculation results according to current national annex (Eurocode) which is presented in a report for easy printout. The calculation results are saved in the impact database and visualized in the IMPACT Project Manager 3D view.


key results straight into the drawing. A more in-depth examination of results can be done in the accompanying PRE-Stress file.

Gapa Project Partners use PRE-Stress to design Roof Beams

Flaviu Popescu from StruSoft Denmark sat down with our PRE-Stress users from Gapa Project Partners Romania and talked about how they are using the program in their design.

Flaviu Popescu: Hi Bogdan, thank you for taking the time to speak to me. I'll just jump right to it: Why did you choose to work with PRE-Stress? What were you using before that?

Bogdan Buzaianu: Before PRE-Stress, we would use an in-house developed spreadsheet to do our verifications. A lot of verifications. We would calculate tension losses, concrete stresses in the initial and final stages, long term effects, SLS checks like deflection, crack width and ULS checks for bending and shear. The disadvantage was the low number of sections for which we did the verifications - basically midspan and supports. 

FP: So what does PRE-Stress help you with the most? 

BB: It saves a lot of time on checking intermediary sections and stages, from release to final stages in ULS. We can cover a large number of situations for release, transport, erection, secondary element erection, short- and long-term ULS checks.  

FP: Do you have a favorite feature in PRE-Stress?

BB: I think the most useful check is the crack width calculation. Before PRE-Stress, in order to limit the calculation stress and concrete crack, we would have to limit the strain in the bottom part of the element. Now we can push the limits a little bit further and have an ever more effecient design. Another very useful features is the posssibility to import sections from a dwg file for hollow core sections with irregular contour. When we have to consider topping, we really appreciate the possibility to model the topping - in the erection phase and as part of the structural element in later phases, all while considering a different concrete class.

FP: What kind of projects and/or elements do you use PRE-Stress for?

BB: The last project we used PRE-Stress on is finalizing now and is a storage warehouse of approximately 7000 m², close to Bucharest, Romania. We used PRE-Stress for calculating the roof beams, spanning 24m² and the slab elements for the administrative building: mainly T and L beam elements and double T surface elements.

FP: Thank you for the great feedback, I'm happy you are finding it useful. You've already said so many good things about PRE-Stress and how it helps your design, anything else you would like to add?

BB: We haven't looked into the Fire Design feature, but we can't wait to use it for our hollow-cores and beam elements!
