The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses. RFEM also determines the stress ranges. Furthermore, it is possible to determine strains for surfaces and solids.
During the stress analysis, the maximum stresses of solids, surfaces, and line welds (RFEM only), as well as of members are determined. The governing internal forces are also documented for each member and surface. Furthermore, there is the option of an automatic section or thickness optimization including the update of the sections or surface thicknesses modified in RFEM/RSTAB.
This manual describes the Stress-Strain Analysis add-on for the programs RFEM 6 and RSTAB 9.
The Construction Stages Analysis (CSA) add-on allows you to represent the construction process of the model in the RFEM 6 program. In this way, you can add, remove, or adjust structural objects to the individual construction phases. Furthermore, you can use the add-on can to determine the sequence of the load application and the way how the load cases are combined within the construction stages.
This manual describes the topics of the webinar "Modeling and Design of Solid Elements in RFEM 6".
In the webinar, a splice with bolts is modeled. It explains how you can define the contact between solids and perform a stress-strain analysis. Furthermore, the utilization of welds is also considered.
