RSTAB - Structural Frame & Truss Analysis Software
Structural Engineering Analysis & Design Software
The 3D structural frame analysis program RSTAB is the ideal tool for the design of beam, frame, or truss structures consisting of steel, reinforced concrete, timber, aluminum, or other materials.
With RSTAB you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. For further design, there are various add‑on modules available, considering structural data of specific materials and standards.
Linear and Nonlinear Structural Analysis
The model is calculated linearly according to the linear static analysis or nonlinearly according to the large deformation analysis. In order to determine internal forces, results can be superimposed in combinations.
Individual Setting of Calculation Parameters
All member types can be calculated according to the linear static, second-order or large deformation analysis. The selection option is available for load cases and load combinations. Further calculation parameters are individually adjustable for load cases, load and result combinations. Thus, high flexibility regarding the calculation method and detailed specifications is ensured.
Incremental Load Application
Loads can be applied incrementally. The increment option is especially useful for calculations according to the large deformation analysis. For members, you can consider shear deformations and apply internal forces to a deformed or undeformed structural system. In addition, RFEM allows you to perform post‑critical analysis.
Analysis of Independent Substructures
It is possible to calculate independent substructures. Deformation development is displayed in a diagram during the calculation. In this way, you can easily evaluate the convergence behavior.
Simple Application of Imperfections
Imperfections can be applied to members, member lists, and sets of members. The numbering of members is irrelevant in this case. The SUPER‑RC add‑on module allows for a multi‑combination of several structures, combining load cases of different files. In this way, you can determine different construction stages.
