Pushover Analysis Software
3D Finite Element Analysis and Design
Structural engineering FEA software RFEM is the basis of a modular software system. 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.
Pushover Analysis
In RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.
This FAQ describes the procedure:
Add-on Modules for Dynamic and Seismic Analysis
The RF‑/DYNAM Pro add-on modules allow for determination of natural vibrations, equivalent seismic loads, and so on.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.

Determination of Pushover Curves
Pushover analysis is a nonlinear structural calculation for the seismic analysis of structures. The load pattern is inferred from the dynamic calculation of equivalent loads. These loads are increased incrementally until global failure of the structure occurs. The nonlinear behavior of a building is usually represented using plastic hinges.
Considering the Stiffness of Gas Solids in Nonlinear Time History Analysis
The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
