RSTAB is the program used to design frameworks.

Input of structure, loads and load combinations, calculation of deformations, internal and support forces for 2D and 3D frame structures

Ultimate limit state design, serviceability limit state design and fire protection design according to DIN 1052:2008-12, EN 1995-1-1:2004+A1:2008 and SIA 265:2003

Critical load factors, effective lengths and buckling shapes

Dowel connections with slotted sheets

In combination with the CAD software by S&S Datentechnik, Bergisch Gladbach (Germany), you can use RSTAB to create and calculate house roofs and even entire house structures. Based on the CAD model RSTAB automatically generates a structural model including basic load cases. In addition to the main program RSTAB and the add-on module TIMBER Pro, appropriate CAD software is required which is listed below: 

CAD programs providing an export option for structural models to RSTAB:

RFEM is the FEA program used to design structures consisting of members, plates and surfaces. 

Input of structure, loads and load combinations, calculation of any 3D structural system including members and surfaces
