Cable and Tensile Structures

In addition to determining loads, some particularities concerning the load combinatorics in timber design have to be considered. Contrary to steel structures, where the largest loading results from all unfavorable actions, in timber construction, the strength values depend on the load duration and timber humidity. Special characteristics have to be considered as well for the serviceability limit state design. The following article discusses the effects on the design of wooden elements and how this is possible with RSTAB and RFEM.

RF-/JOINTS Timber – Timber to Timber allows you to design main-connected beam joints. This article explains the determination of forces in screws of a beam connected to a torsionally rigid main beam.

In this article, the design of a timber panel wall with the beam panel thickness type is performed.

First, select the joint type and the design standard.

The connected members are imported from the RFEM/RSTAB model. The add-on module automatically checks if all geometry conditions are fulfilled.

In addition, the loads are imported automatically from RFEM/RSTAB. In the Geometry window, you can specify the screw parameters (diameter, length, angle, and so on).

• Design of hinged connections
• Biaxial inclination of the connected member (for example, a jack rafter joint)
• Connection of any number of members on one node for the type "Main member only"
• Screw diameter 6 mm – 12 mm
• Automatic check of the minimum distance between screws
• Optional free definition of screw distances
• Transfer of eccentricity from RFEM/RSTAB
• Crosswise or parallel screw alignment
• Definition of up to 16 screws in a row
• Graphical visualization of joints in the add-on module and in RFEM/RSTAB
• Performing all required designs

 

In the material library of RFEM, you can find plywood materials according to the US and Canadian standards ANSI/APA PRG 510 Plywood (USA/CAN).
