Nonlinear Dynamic Analysis Software

Nonlinear Time History Analysis of Structures

Use the structural analysis software RFEM and RSTAB to perform nonlinear dynamic analyses of structures for a time history analysis. For this task, we provide you with the nonlinear analysis method.

RFEM and RSTAB offer you a wide range of options. Among other things, you can calculate nonlinear member types (tension and compression members as well as cables) and member nonlinearities (failure, yielding, and so on). Moreover, support nonlinearities (failure, friction, and so on) and release nonlinearities are also considered in RFEM and RSTAB.

Structural FEM Analysis and Design

Are you looking for a digital assistant for your construction project? 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. Does your project include different elements? That is not a problem for RFEM. The program also allows you to create combined structures as well as to model solid and contact elements.

Structural Frame & Truss Analysis Software

The structural frame & truss analysis software RSTAB 8 is a bit slimmer. It has a similar range of functions as the FEA software RFEM, but a special attention is paid to beam, frame, and truss structures. It is thus very easy to use. RSTAB 9 has been the best choice for structural analysis and design of pure structural member models for many years. Are you interested? Read more here:

Determination of Natural Frequencies and Mode Shapes

Are you looking for a way to determine natural frequencies and mode shapes? Then you are right here! Use the RF‑/DYNAM Pro - Natural Vibrations add-on module for RFEM 5& / RSTAB& 8 to see that the calculation is not only easy, but also realiable.

Forced Vibration Analysis

The RF‑/DYNAM Pro - Forced Vibrations add-on module for RFEM 5 / RSTAB 8 provides you with several methods that you can use for your project. The module performs the analysis of forced vibrations including the multi-modal response spectrum analysis and the time history analysis.

Nonlinear Time History Analysis

Do you need more options in RFEM& 5 / RSTAB& 8? Is a nonlinear time history required for your project? Then we have the right thing for you: 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). Try it yourself!

Interfaces for Data Exchange

Another argument that speaks for Dlubal Software is the flexible integration into the Building Information Modeling (BIM) process. The structural analysis programs have a large number of interfaces available for you. You can thus exchange data of digital building models with RFEM or RSTAB.

Use the Webservice (a programmable interface) to read and write the required data from or to RFEM and RSTAB.

Response Spectrum Analysis

Dynamic Analysis

In the Response Spectrum Analysis add-on, seismic analysis is performed using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from this. The add-on includes an extensive library of accelerograms from seismic zones. These can be used to generate response spectra.

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.
