In this article, you will learn how to model and design cable structures in RFEM 6 or RSTAB 9.
![KB 001879 | Influence of Bending Stiffness of Cables](/en/webimage/049953/3835546/Seil.png?mw=512&hash=83e64fde3c3d0a1d2649d8e64587b93f4ab71876)
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.
![KB 001877 | ASCE 7-22 and NBC 2020 Seismic P-Delta Considerations in RFEM 6](/en/webimage/048528/3803808/Image_01_-_Interstory_Drifts.png?mw=512&hash=dda93b6dc2bff834091aa0c09a68a55dab800606)
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.

The data exchange between RFEM 6 and Allplan can be done using various file formats. This article describes the data exchange of a determined surface reinforcement using the ASF interface. This allows you to display the RFEM reinforcement values as level curves or colored reinforcement images in Allplan.
![Feature 002827 | Stresses Within Members](/en/webimage/050679/3922742/50679.png?mw=512&hash=89c2586ec7139690a213073aaa5a3e314c7ed023)
Get a better understanding of the stress distribution within member cross-sections by using clipping planes.

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".
![Feature 002823 | Generate Bracing in Cells](/en/webimage/050459/3889302/1.png?mw=512&hash=9d7f6c198b6d4ae6ee8f2fa8bca75f85579e14c9)
The "Bracing in Cells" function allows you to generate diagonal bracing with just a few clicks. You can find this feature under Tools → Generate Model – Members → Bracing in Cells.
![Feature 002819 | Flow Field Quantities](/en/webimage/050342/3881104/1.png?mw=512&hash=9d7f6c198b6d4ae6ee8f2fa8bca75f85579e14c9)
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
