Analysis & Design Software for Silos and Storage Tanks
FEM Analysis and Design of Structures
The RFEM program is the basis of a modular software system. 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. The program also allows you to create combined structures as well as model solid and contact elements.
Wind Simulation & Wind Load Generation
Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Actions on Silos According to EN 1991-4
Silos are used as large containers for storing bulk materials such as agricultural products or source materials as well as intermediates of industrial production. Structural engineering of such structures requires a precise knowledge of the stresses due to particulate solids in the building structure. The standard EN 1991‑4 ‘Actions on Silos and Tanks’ [1] provides general principles and requirements for determining these actions.
Calculation of Stiffened Buckling Panels According to EN 1993-1-5, 4.5
In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5.
The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
- How do I determine wind loads on structures of any shape?
- How can I apply the wind load by an angular function to the surface (for example, a grain silo, curved wall, etc.)?
- I am looking for a way to automatically generate special structures or to call them with parameters.
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- How can I deduce the axial stress and hoop stress of a circular container?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
-
How can I perform a stability/buckling analysis on a load-bearing structure?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- Is it possible to use RFEM for modeling a channel that is distorted from a rectangular cross-section to a pipe cross-section?
