Analysis & Design Software for Silos and Storage Tanks
The structural analysis software RFEM 6 is the basis of a modular program family. The RFEM main program 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.
The RWIND 2 stand-alone program is recommended 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.
For the structural analysis and design of silos and storage tanks, we recommend the add-ons and add-on modules of the Steel Structures industry.
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.
The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
The butadiene storage tanks of the French company ARLANXEO Emulsion Rubber France, one of the biggest producers of NBR synthetic rubber in the world, had to be recalculated to comply with the seismic requirements of Eurocode 8.
Aquamate, a leading manufacturer of corrugated water tanks in Australia, plans to enter the North American market by the end of 2016.
Therefore, it is necessary to verify that the tanks meet all US codes and standards before the end of the year.
This project for designing a filter/dryer device, including agitator, required a complete stress and deformation analysis in RFEM.
The complex modeling of the structure, which had 1,424 surfaces, 158 solids, and 425 members, represented a special design challenge.
On the site of Baumit GmbH in Landsberg/Lech, a second mixing plant for ground building materials was built in 2015.
The steel structure supports the silo grating located at +85 ft which includes a total of 36 silos.
The 100-year-old gasometer in Pforzheim, Germany, was threatened with demolition.
The steel structure of the former gas storage facility has been transformed into an extraordinary event area for the 360° panorama exhibition.

Silos are used as large containers for storing bulk materials such as agricultural products or source materials, as well as intermediates of industrial production. The 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"  provides the general principles and requirements for determining these actions.
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, and so on)?
- I am looking for a possibility to automatically generate special structures or to load the parameterized structures.
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- How can I apply wind load distribution to a cylinder according to EN 1991‑4, Section 7.9?
- 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?
- I have calculated a box girder. Which surface results or surface stresses can I use to evaluate the buckling behavior of the web plates?
- 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?
