Structural Analysis Models to Download
You can download here a wide range of structural models (for example, RFEM, RSTAB, or RWIND files) that you can use for training purposes or for your projects.
Frequently Asked Questions (FAQ)
- Which programs can I use to calculate and design power plants?
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- How do I display the nodal displacements graphically?
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- How can I quickly transfer a load from one load case to another? I have entered my loads into an incorrect load case by mistake.
- Regarding a nonlinear analysis of reinforced concrete, is there any feature in the program that increases the load until failure? Or is there any way how to describe the load increment until failure?
