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

17 October 2017

RFEM and RSTAB allow you to easily consider wind load effects on a three-dimensional building according to ASCE/SEI 7‑16 [1]. This article explains the complex theory of entering wind loads in the software.

Displaying Curtailment of Longitudinal Reinforcement and Reinforcement Covering Line

12 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.

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.

Visual Model Check Using Print to 3D PDF

10 October 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

6 October 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 (C) and modelling options (M). Both the calculation methods and the modelling options are not limited to T‑beams, but will only be explained using an example of this system.

Hardening Parameters in Nonlinear Material Models

4 October 2017

Strain hardening is the material ability to reach a higher stiffness by redistributing (stretching) microcrystals in the crystal lattice of the structure. A distinction is made between the material isotropic hardening as scalar quantities or tensorial kinematic hardening.

Influence of Ground Water Level on Design in RF-/FOUNDATION Pro

2 October 2017

Using RF‑/FOUNDATION Pro, it is possible to perform geotechnical design according to EN 1997‑1 [1] for single foundations. Subsequently, the program displays detailed information about the influence of the ground water level on the selected design according to EN 1997‑1.

Conceptual Design of Wolbecker Road Bridge No. 76 in Münster, Germany

28 September 2017

Starting in 2018, an architecturally appealing tied‑arch bridge will arise in Münster, Germany. The new road bridge will be built over the Dortmund‑Ems Canal with a span of 67.20 m. It will replace the existing classic arch bridge, built in 1957, which is 5 m less in span length.

COM Interface in VBA | 4.2 Frame Optimisation

26 September 2017

Part 4.1 described the linking of the RF‑/STEEL EC3 add-on module. Furthermore, the members and the load combinations which should be designed have been already defined. Part 4.2 focuses on cross-section optimisation in the add-on module and the export to RFEM.
