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.
