Stress-Strain Analysis for RFEM 6 / RSTAB 9
Stress Analysis of Members, Surfaces, and Solids
Customer Projects
The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses.
During the stress analysis, the add-on determines the maximum stresses of solids, surfaces and surface sets (RFEM only), as well as members and member sets. The governing internal forces are also documented for each member. In addition, there is the option of an automatic section or thickness optimization including the export of the modified sections or surface thicknesses to RFEM/RSTAB.

Results
After the calculation, the resulting maximum stresses and stress ratios are displayed sorted by section, member/surface, solid, member set, x-location, and so on. In addition to the tabular result values, the corresponding cross-section graphic with stress points, stress diagram, and values is displayed as well. The design ratio can be related to any kind of stress type. The current location is highlighted in the RFEM/RSTAB model.
In addition to the tabular evaluation, it is possible to graphically check the stresses and design ratios on the RFEM/RSTAB model. It is possible to individually adjust the colors and values.
Result diagrams of a member or set of members facilitate targeted evaluation. Furthermore, you can open the respective dialog box of each design location to check the design-relevant section properties and stress components of any stress point. You can print the corresponding graphic, including all design details.

Member Transverse Stiffeners in RFEM 6 and RSTAB 9
This article shows you how to define different types of member transverse stiffeners in RFEM 6 and RSTAB 9. It also shows you how to consider them in the design as well as the calculation of members with 7 degrees of freedom.

The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations?
- How do I include the redundancy factor(s), ρ in the ASCE 7 load combinations?
- I do not see the seismic load cases in my generated ASCE 7 load combinations (COs). How do I add them?
- How do I create an imperfection based on a mode shape in RFEM 6?
-
How do I apply the ASCE 7 Orthogonal Directional Combination procedure (100% + 30% rule) to my seismic load in a static analysis?
- Is it possible in the CRANEWAY software to obtain the SLS rotational deformations of a continuous beam at the supports for an isostatic beam in the web plane?

Special Solutions
First, the two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Second, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
