Member Type "Cable on Pulleys"

The Cable on Pulleys member type allows you to simulate a cable system deflected by pulleys.

This member type only absorbs tensile forces and can only be displaced in the longitudinal direction. It is suitable for flexible tension elements whose longitudinal forces are transferred through the model via deflection points (for example, a pulley).

The image shows the “Cable on Pulleys” member type, which absorbs only tensile forces and is simulated as a pulley system.

Excel Data Imported into RFEM for Variable Member Load
The ASCE 7-22 standard requires both balanced and unbalanced snow load case scenarios for a structure's design consideration. While this may be more intuitive for flat or even gable/hip type roofs, the determination of snow loads is increasingly difficult for arch roofs due to complex geometry. However, with guidance from ASCE 7-22 on snow load calculations for curved roofs and RFEM's efficient load application tools, it is possible to consider both balanced and unbalanced snow loads for a reliable and safe structure design.
Experimental Wind Tunnel Test – Aachen University
Validating CFD simulations with experimental data enhances accuracy by comparing simulation outcomes with real-world conditions. This process identifies discrepancies, allowing adjustments to enhance model reliability. Ultimately, it builds confidence in the simulation's ability to predict wind load scenarios.
KB 001884 | AISC Chapter F Lateral Torsional Buckling Versus Eigenvalue Calculation Methods Compared in RFEM 6
Utilizing the Steel Design Add-on, steel design is possible according to the AISC 360-22 standard. The following article will compare the result output when calculating lateral torsional buckling according to Chapter F vs. an Eigenvalue Analysis.
Basic Shapes of Membrane Structures [1]
This paper is focused on the specific aspects of designing membrane structures that have specific requirements, such as form-finding and cutting pattern generation. An integral part of the design of these structures is the process of finding suitable prestressed shapes and generating cutting patterns. The text briefly describes two basic processes in the design of membrane structures. The physical principles are explained and the individual theses illustrated by examples.

Feature 002423 | Displaying Results in Solids

The results of solid stresses can be displayed as colored 3D points in the finite elements.

Feature 002012 | Generation of Snow Loads

Do you want your structures to remain upright even in wind and snow? Then rely on the load wizards for plate and frame structures. You can now generate wind loads according to EN 1991‑1‑4 and snow loads according to EN 1991‑1‑3 (as well as other international standards). The load cases are generated depending on the roof shape.

Feature 002013 | Generation of Wind Loads

Wind loads are also not a problem in your design. You can automatically generate wind loads as member loads or area loads (RFEM) on the following structural components:

  • Vertical walls
  • Flat roofs
  • Monopitch roofs
  • Duopitch/troughed roofs
  • Vertical walls with duopitch roof
  • Vertical walls with flat/monopitch roof

The following standards are available to you:

  • European Union | Flag EN 1991-1-3 (incl. National Annexes)
  • EN-US | Flag ASCE 7
