Model and Design Aluminum Structures in RFEM 6 and RSTAB 9

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.

In addition to JavaScript, the Python high-level functions are also available in the console. Using the Python option, the console also provides you with the Python HLF functions known from the WebService function catalog for further use in the object properties dialog box for in-app scripting.

In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
