Dynamic and Seismic Analysis Software

Dynamic and Seismic Analysis of Structures

Dynamic analyses are an important part of the structural analysis and design. Different application areas get together here. Typical dynamic analyses cover seismic design (earthquake), vibration design of buildings, calculation of machine foundations, as well as natural frequency analysis of bridges and chimneys.

If you want to carry out such analysis on your project digitally, you are at the right place. For the structural FEA software RFEM and the structural frame analysis software RSTAB, we offer a wide range of powerful add-on modules that you can use to perform your dynamic calculations without much effort.

Structural FEM Analysis and Design

To ensure stability in any situation, your structural project needs a stable foundation. The basis for your planning is the structural analysis program RFEM 6. Various modules build on this program that you can compile according to your needs. Use the main program RFEM to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Is your project diverse? Dlubal Software too! Because it is possible to create combined structures as well as to model solid and contact elements.

Structural Frame & Truss Analysis Software

The structural frame and truss analysis software RSTAB 9 has similar functions as the FEA software RFEM. Due to its special attention to beam, frame, and truss structure, RSTAB is very easy to use. Try out RSTAB 9 and join many structural engineers who appreciate the reliable structural frame & truss analysis program for years.

Determination of Natural Frequencies and Mode Shapes

Natural frequency vibrations can be very dangerous for construction projects. Therefore, the analysis of natural frequencies is very important for the long-term stability of your project. 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

Earthquake, along with the fire and other natural forces, are the greatest threat to construction projects. Do you want to be prepared for all eventualities? In the Response Spectrum Analysis add-on for RFEM 6 / RSTAB 9, the seismic analysis is performed using the multi-modal response spectrum analysis. You can create the response spectra required for this in compliance with the standards or user-defined. The program use them to generate the equivalent static forces. It means your construction project is still on a solid footing, even in the event of an earthquake.

Forced Vibration Analysis

For your vibration analysis, there are several methods in one module. We provide this practical package as the RF‑/DYNAM Pro - Forced Vibrations add-on module for RFEM 5 / RSTAB 9. It allows you to analyze forced vibrations. Moreover, the multimodal response spectrum analysis and the time history analysis are available here.

Nonlinear Time History Analysis

The add-on modules RF‑/DYNAM Pro - Natural Vibrations and RF‑/DYNAM Pro - Forced Vibrations (linear time history analysis) are not enough for you? Do you also need a nonlinear time history for your calculations? We have a solution for you. RF-/DYNAM Pro - Nonlinear Time History for RFEM 5 / RSTAB& 8 is an extension that is definitely worthwhile. Read more about it:

CADS Footfall Analysis

Footfall Analysis is a post-processing software that was developed by the English company CADS. You can use this program in conjunction with RFEM 5 and RF‑DYNAM Pro - Natural Vibrations to obtain calculations for an impact noise frequency analysis.

Interfaces for Data Exchange

The reliable data exchange between our software programs ensures that you can easily integrate the Dlubal structural analysis software into the Building Information Modeling (BIM) process. Thus, a large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.

Use the Webservice (a programmable interface) and you will see: The data can be easily read and write from or to RFEM and RSTAB.
