Nonlinear Dynamic Analysis Software
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.
