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 frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural engineers.
RF-/STEEL Warping Torsion is an extension of the RF-/STEEL AISC and RF‑/STEEL EC3 add‑on module. It performs flexural-torsional and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.

A remarkable free‑form roof structure was built at the Xujiahui Commercial Center in Shanghai, China, and inaugurated in June 2017.
It serves as a skylight in the indoor area of the shopping center, and as a canopy in the outdoor area.
The Müngsten Viaduct, completed in 1897, ranks among the most important buildings in steel bridge construction in the world today.
With a height of 351 ft over the Wupper River, it is Germany's highest railway bridge.
A unique structure called Sky Walk has been built in Dolní Morava, Czech Republic, under the Králický Sněžník mountain at a height of 3,661.4 ft, and is unprecedented in Central Europe.
Sky Walk is a look‑out trail leading up to 192 ft above the surrounding hilly terrain level, being visible at a distance of several miles.
An architectural highlight of the Kauffman Center for the Performing Arts is the glass atrium.
The glass facade and the glass skylight are supported entirely by the cable structure. The design was conceived as a cello’s strings fanning over a bridge and fret-board.
The "Hemsedal Ski Center" in the Scandinavian Alps is one of the top 3 ski resorts in Norway with a total of 49 ski slopes and 20 surface lifts.
At the foot of the mountainside, a new steel & reinforced concrete building of an apartment hotel with 100 modern rooms will be completed by the end of 2017.
The Ferrari World Theme Park on the Yas Island, UAE, is an amusement and recreation park including the Formula 1 racing circuit, a shopping mall, several luxury hotels and two golf courses.
The gigantic free-formed roof of the Ferrari World is the largest spatial framework ever built.
From architectural point of view, the most impressive structural component of the extended shopping mall Centrum Černý Most in Prague, Czech Republic is the partially glazed roof over the food court.
This is where the design of the featured steel structure found its use.
The multifunctional two-tier stadium with 30,000 seats was built in Uyo, Nigeria.
The stadium with the ornamental façade consists of two separate steel structures - the stand area with rounded corners and the VIP box.
The 100-year-old gasometer in Pforzheim, Germany, was threatened by demolition.
The steel structure of the former gas storage facility has been transformed to an extraordinary event area for the 360° panorama exhibition.
A very extraordinary structure has been built in Chile: the "temple of light" which is one of eight Bahá’í temples worldwide.
The unique building resembles a nine‑petalled blossom of a lotus flower.
The following article describes the design of a single‑span beam subjected to bending and compression, which is performed according to EN 1993‑1‑1 in the RF‑/STEEL EC3 add‑on module. Since the beam is modelled with a tapered cross‑section, thus not a uniform structural component, the design must be performed either according to General Method in compliance with Chap. 6.3.4 of EN 1993‑1‑1, or according to the second‑order analysis.
The module extension RF‑/STEEL Warping Torsion of the RF‑/STEEL EC3 add‑on module allows you to design members with asymmetric cross‑sections. The new option is fully integrated in the design module and can be activated for sets of members.

Dlubal Webinar: AISC 360-16 Steel Member and Warping Torsion Design in RFEM
The member hinge nonlinearities "Scaffolding - N phiy phiz" and "Scaffolding Diagram" enable the mechanical simulation of a tube joint with an inner stub between two member elements.
The equivalent model transfers the bending moment via the overpressed outer pipe and after positive locking additionally via the inner stub, depending on the compression state at the member end.
