The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 2, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.
The specific soil material models have a variable stiffness that depends, among other things, on the prevailing stress level.
In the analysis of a single load case, this is only impressed on the structure and the soil. No stress level from other loads is taken into account, which might be necessary to obtain and use the correct soil stiffness from the soil material model.
The load case of a live load, for example, will result in different stiffnesses and thus deformations,if it is applied within a load combination on a structure that is already subjected to the soil weight as well as the structural weight and construction load,than it would result if setting it as the "first/single" load, which would be done in the analysis of the load case.
Therefore, it does not make sense to analyze the soil with the specific soil material models subjected to the individual loads / load cases if at least the always prevailing soil self-weight is not taken into account.
