Add-on Module for RFEM 5
RF-HOLLOW SECTION

The RF-HSS add-on module is used for the structural design and analysis of various hollow section connections. This includes the calculation of planar and spatial truss nodes, which may consist of circular, square, or rectangular hollow sections.

This add-on module is integrated seamlessly into RFEM 5, so it automatically recognizes the geometry and allows for manual definition of joints. It provides you with an extensive library of hollow sections for chords and struts, the option to select joint types according to standards and partial safety factors of different countries, and other features.

RF-HSS Manual | Input

It is possible to select connection nodes graphically in the RFEM/RSTAB model. The relevant cross-section data and geometry are imported automatically. You can also define the parameters of hollow section connections manually. If necessary, you can modify the sections in the module.

The default angle between struts and chords can be modified as well. The geometric relation of the struts to each other is important for the correct choice of design. This relationship can be defined by specifying a gap between the struts or by overlapping them.

RF-HSS Manual | Design

A successful design check is based on the plausibility check of the geometric conditions.

The RF-/HSS add-on module performs the calculation for the following designs:

Flange failure of chord member due to normal force
Shear failure of chord member due to normal force
Strut failure due to normal force
Punching shear due to normal force

RF-HSS Manual | Results

The design includes detailed information about analyzed internal forces, validity limits, and design conditions. Design failures are clearly marked in the result overview.

All input and result data are also documented in the general RFEM/RSTAB printout report. Separate design cases allow flexible analysis of the individual components in large structures.
