In this article, you will learn how to model and design cable structures in RFEM 6 or RSTAB 9.
This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
The ASCE 7-22 Standard [1], Sect. 12.9.1.6 specifies when P-delta effects should be considered when running a modal response spectrum analysis for seismic design. In the NBC 2020 [2], Sent. 4.1.8.3.8.c gives only a short requirement that sway effects due to the interaction of gravity loads with the deformed structure should be considered. Therefore, there may be situations where second-order effects, also known as P-delta, must be considered when carrying out a seismic analysis.
This article presents the basic concepts in structural dynamics and their role in the seismic design of structures. Great emphasis is given to explaining the technical aspects in an understandable way, so that readers without deep technical knowledge can gain an insight into the subject.

The STEP format represents a standard interface initiated by ISO (ISO 10303). In the topology specification, all shapes (line, surface, and solid models) relevant for RFEM can be transferred from CAD models.
Note: This format is completely different from the product interface DSTV (Deutscher Stahlbau Verband), which uses the same file extension *.stp.
The Initial Graphics Exchange Specification (IGES) defines a neutral, highly independent data format, which is used to exchange digital information among Computer Aided Design (CAD) programs.
The ACIS SAT file format is smaller than other 3D formats, saving you time when importing and exporting models. The export currently supports the ACIS 7.0 format.
In addition, SAT is considered to be particularly robust, and all geometry and topology data, where relevant in RFEM, are retained in the highly accurate SAT models.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
