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.
Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to frame and beam structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analyses.
RF-MAT NL allows you to apply the nonlinear material laws in RFEM.
RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add‑on module. It allows for plastic design of cross‑sections according to Partial Internal Forces Method or Simplex Method.
RF-CONCRETE NL performs physical and geometrical nonlinear calculation of beam and plate structures consisting of reinforced concrete.
RF-CONCRETE Deflect allows for analytical deformation analysis of plate structures consisting of reinforced concrete.

Since August 2014, there is a new extraordinary outdoor theater in Bytom, Poland.
From the structural engineering point of view, the timber structure consists of two parts (the theater stage and backstage) geometrically interconnected together by a spatial-shaped roof. This gives the structure its remarkable design.

A new architectural highlight in the capital of the United Arab Emirates is the dome of the Louvre Abu Dhabi.
The structure consisting of steel has a diameter of 180 m and covers the new local branch of the Louvre Museum in Paris.

For renovations of the steeple in the St. Martinus parish in Kerpen, a scaffold was required.
The designers had to meet a special challenge as the frame construction had to be set up at the spire top without applying anchorages by pressure usually used in scaffolding.

A glass pedestrian bridge with a length of 30 m connects the St. Michael hospital with the research center Li Ka Shing Knowledge Institute.
The supporting structure consists of several oval steel rings which are twisted together.

The Kuchlbauer tower is an architectural project built on the premises of the German brewery Kuchlbauer in Abensberg.
The tower was designed by F. Hundertwasser, who died in 2000 when the project was still in its planning stages.

A very special project was carried out in Pitigala, Sri Lanka in 2013. A suspension bridge was designed, calculated and built by 30 students of the university team "Engineers Without Borders".
The 30-meter-long bridge across the Bentara river with was constructed with pure man power.

A unique roof structure was built for the main bus station in Aarau, Switzerland in 2013.
The canopy has a cloud-like shape and contains the largest single‑chamber cushion in the world. The ETFE cushion has a volume of 63,919.55 ft³ and covers an area of 11,517.38 ft².

Different methods are available for calculating the deformation in the cracked state. RFEM provides an analytical method according to DIN EN 1992-1-1 7.4.3 and a physical-nonlinear analysis.
In RFEM, there is an option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (RF-MAT NL add-on module required).
This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.
