The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.

Stability Analysis of Building Structure

Structure Stability for RSTAB 9

The Structure Stability add-on for RSTAB 9 allows you to perform efficient stability analyses. Use this powerful tool to determine critical load factors and the corresponding stability modes without performing complex manual calculations. You can calculate models consisting member elements, perform nonlinear stability analyses, and consider initial prestresses.

The selection of equation solvers and the possibility to consider the stiffness modifications in RSTAB make it a versatile tool for your stability analysis. Furthermore, the add-on supports both linear and nonlinear analysis, providing various calculation methods to determine the local buckling of single members. The results, including the standardized mode shapes and critical loads, are displayed in a clearly arranged way to facilitate the evaluation of stability risks.

Torsional Warping (7 DOF) for RSTAB 9

Do you want to calculate members? The Torsional Warping (7 DOF) add-on allows you to consider the cross-section warping as an additional degree of freedom when calculating members in RSTAB. Thus, you have more options.

degree of freedom directly into your model, and thus the stiffnesses of the connected elements are realistically considered without the need for equivalent spring stiffnesses or special support conditions. The add-on allows for a detailed analysis of seven local deformation directions and eight internal forces, which is especially crucial when calculating stability issues, such as torsional buckling and lateral-torsional buckling.
