Nonlinear Dynamic Analysis Software

Nonlinear Time History Analysis of Structures

When performing dynamic analyses of structures, it is often necessary to consider nonlinear member types (tension or compression members, cables), or various member, support and release nonlinearities.

The FEA software RFEM as well as the frame & truss analysis software RSTAB allows you to perform time history analysis considering such nonlinearities.

Structural FEM Analysis and Design

The structural analysis software RFEM 5 is the basis of a modular program family. The main program 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.

Structural Frame & Truss Analysis Software

The structural frame and truss analysis software RSTAB 8 has similar functions as the FEA software RFEM. Due to the special attention to beam, frame, or truss structures, it is very easy to use and for many years, it has been the best choice for structural analysis and design of pure structural member models.

Determination of Natural Frequencies and Mode Shapes

The RF‑/DYNAM Pro - Natural Vibrations add-on module for RFEM 5 / RSTAB 8 determines natural frequencies and shapes.

Forced Vibration Analysis

The RF‑/DYNAM Pro - Forced Vibrations add-on module for RFEM 5 / RSTAB 8 performs the analysis of forced vibrations including the multi-modal response spectrum analysis and the time history analysis.

Nonlinear Time History Analysis

RF-/DYNAM Pro - Nonlinear Time History for RFEM 5 / RSTAB 8 is an extension of the add-on modules RF‑/DYNAM Pro - Natural Vibrations and RF‑/DYNAM Pro - Forced Vibrations (linear time history analysis).

Interfaces for Data Exchange

The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.

The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
