Frame Analysis Software RSTAB 9 | Calculation

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. Various add-ons that take into account the material and standard-specific requirements are available for the design.

Linear and Nonlinear Structural Analysis

Structural Analysis Models to Download

Models to Download

Select numerous structural models to utilize them for training purposes or for your projects.

The model is calculated linearly according to the linear static analysis or nonlinearly according to the second-order or large deformation analysis. In order to determine internal forces, results can be superimposed in combinations.


Individual Setting of Calculation Parameters

The calculation can be performed for all member types according to the linear static, second-order, or large deformation analysis. This selection option is available for load cases and load combinations. Additional calculation parameters are individually adjustable for load cases, load combinations, and result combinations. This ensures a high degree of flexibility with regard to the calculation method and detailed specifications.


Optional Incremental Load Application

The loading can be applied incrementally. This option is particularly suitable for calculations according to the large deformation analysis. In addition, RFEM allows you to perform post‑critical analyses.


Computation Kernel with Multi-Core Processor Technology

The calculation is now optimized utilizing a multi-core processor termology. It enables parallel calculations of linear load cases and load combinations by several processors without additional demands on the RAM: The stiffness matrix has to be created only once. Thus, even large systems can be calculated with the fast direct solver.

For models requiring the calculation of multiple load combinations, several solvers (one per core) are initiated in parallel. Each solver then calculates a load combination. This leads to a better utilization of the cores.

The development of the deformation is displayed in a diagram during the calculation. This allows for good assessment of the convergence behavior.

Special Solutions

First, the two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Second, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
