New Add-on Module RF-/JOINTS Timber - Timber to Timber

19 October 2017

RF-/JOINTS Timber - Timber to Timber designs joints where timber members are directly connected to each other by means of slant screws. The design is performed according to EN 1995‑1‑1 (Eurocode 5).

Imperfections According to EN 1993-1-1 Clause 5.3.2: Bow Imperfection

18 October 2017

According to EN 1993‑1‑1, it is necessary to use the equivalent geometric imperfections with values that reflect the possible effects of all types of imperfections. EN 1993‑1‑1, Clause 5.3, specifies basic imperfections for the global analysis of frames as well as member imperfections.

Generating Wind Loads on Walls and Roofs According to ASCE/SEI 7-16

13 October 2017

RFEM and RSTAB allow you to easily consider wind load effects on a three-dimensional building according to ASCE/SEI 7‑16. This article explains the complex theory of entering wind loads in the software.

Oberholz Alpine Hut in Obereggen, Italy

12 October 2017

At a height of around 2,100 m you can enjoy a breathtaking view of the dolomites with a delicious meal.

Since 2016 these amenities have been available at the top station of the Obereggen skiing area, South Tyrol.

Rehabilitation of the Müngsten Viaduct, Germany

11 October 2017

The Müngsten Viaduct, completed in 1897, ranks among the most important buildings in steel bridge construction in the world today.

With a height of 107 m over the Wupper River, it is Germany's highest railway bridge.

Cutting Pattern of Membranes and Cable Elements

10 October 2017

Cable and tensile membrane structures are regarded as very slender and aesthetic building constructions. The partly very complex double-curved shapes can be found using suitable form‑finding algorithms. A possible solution is, for example, to search the form via the equilibrium between the surface stress (provided prestress and an additional load such as self‑weight, pressure, etc.) and the given boundary conditions.

RF-/STEEL AISC Mode Shapes

6 October 2017

After running an analysis in RF‑/STEEL AISC, the mode shapes for sets of members can be viewed graphically in a separate window. Select the relevant set of members in the result window and click the [Mode Shapes] button.

Displaying Curtailment of Longitudinal Reinforcement and Reinforcement Covering Line

4 October 2017

In the case of a huge amount of reinforcement, it might be useful to grade the longitudinal reinforcement of a beam. The grading corresponds to the tensile force distribution. Using RF‑CONCRETE Members and CONCRETE, you can specify the curtailment of the reinforcement, which is considered in the automatically proposed reinforcement for the longitudinal reinforcement.

Visual Model Check Using Print to 3D PDF

28 September 2017

The 3D PDF functionality allows you to display three-dimensional models from RFEM or RSTAB in a 3D PDF. In addition to the general information about the image that can be moved, zoomed or rotated, the 3D PDF also contains 3D information.

Downstand Beams, Ribs, T-Beams: Deformation and Deflection in Cracked State

26 September 2017

RFEM and the RF‑CONCRETE add‑on modules provide various options for the deformation analysis of a T‑beam in cracked state (state II). This technical article describes the calculation methods and modelling options.
