Frame Analysis Software RSTAB 9 | Calculation

Structural Engineering Analysis & Design Software

Calculations may cost you a lot of valuable time. Let RSTAB do the math! Use the successful structural frame & truss analysis software RSTAB for your 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. There are design add-ons at your side that you can use to consider the material- and standard-specific requirements.

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.

Your model is calculated precisely and quickly. The model is calculated linearly according to the linear static analysis, or nonlinearly according to the second-order or the large deformation analysis. In order to determine design internal forces, you can be superimpose the results in combinations.


Individual Setting of Calculation Parameters

Select the individually suitable calculation parameters for your project: You can perform the calculation for all member types according to the linear static, second-order, or large deformation analysis. You have this selection option for load cases and load combinations. You can specifically set further calculation parameters for load cases, load combinations, and result combinations, which ensures a high degree of flexibility with regard to the calculation method and detailed specifications.


Optional Incremental Load Application

This feature helps you with the load application. You can have the required loading applied incrementally. This option is particularly suitable for your calculations according to the large deformation analysis. Furthermore, you can easily perform post‑critical analyses in RFEM.


Computation Kernel with Multi-Core Processor Technology

Also in this case, RSTAB will certainly convince you. With the powerful calculation kernel, its optimized networking and support of multi-core processor technology, the Dlubal structural analysis program is far ahead. This allows you to calculate more linear load cases and load combinations using several processors in parallel without using additional memory. The stiffness matrix only has to be created once. Thus, it is possible for you to calculate even large systems with the fast and direct solver.
Do you have to calculate multiple load combinations in your models? The program initiates several solvers in parallel (one per core). Each solver then calculates a load combination for you. This leads to better utilization of the cores.
You can systematically follow the development of the deformation displayed in a diagram during the calculation, and thus precisely evaluate 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.

Pushover Analysis

Dynamic Analysis

Earthquakes may have a significant impact on the deformation behavior of buildings. A pushover analysis allows you to analyze the deformation behavior of buildings and compare them with seismic actions. Using the Pushover add-on, you can analyze the seismic actions on a particular building and thus assess whether the building can withstand the earthquake.
