Dynamic and Seismic Analysis Software

Dynamic and Seismic Analysis of Structures

Typical application areas for dynamic analysis are seismic design, vibration design of buildings, calculation of machine foundations as well as natural frequency analysis of bridges and chimneys.

The FEA software RFEM and the structural frame analysis software provide a wide range of powerful add-on modules for dynamic analysis.

Structural FEM Analysis and Design

The structural analysis software RFEM 6 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 analysis software RSTAB 9 has a similar range of 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 Modal Analysis add-on for RFEM 6 / RSTAB 9 allows you to determine natural frequencies and mode shapes of member, surface, and solid models.

Seismic Analysis

In the Response Spectrum Analysis add-on for RFEM 6 / RSTAB 9, the seismic analysis is performed using the multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or user-defined. From this, the equivalent static forces are generated.

Forced Vibration Analysis

The RF‑/DYNAM Pro - Forced Vibrations add-on module for RFEM 5 / RSTAB 9 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).

CADS Footfall Analysis

Footfall Analysis is post-processing software developed by CADS that can be used in conjunction with RFEM 5 and RF-DYNAM Pro - Natural Vibrations provide footfall response analysis calculations. 

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.
