Nonlinear Buckling Analysis

Steel stress analysis of frame joint

3D Finite Element Analysis and Design

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

Nonlinear buckling analysis

Stability Analysis According to Eigenvalue Calculation Method

RF-STABILITY determines buckling shapes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behaviour.

Imperfections generated in RF-IMP/RSIMP

Generation of Equivalent Geometric Imperfections and Pre-Deformed Initial Models

RF-IMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.
