Degradation and Strengthening of Beams

In subsequent stages the beams cannot be edited in a standard way. Therefore, one of the following options must be selected to modify them:

  • removing the selected beam from the analysis
  • degrading the selected beam (applicable only in the "Tunnels" mode)
  • strengthening the selected beam cross-section
  • modifying the beam contact properties

The type of modification is selected from the "Adjust beam properties" dialog window.

A degree of beam degradation is specified in percentage, one hundred percent corresponds to beam removal.

Strengthening a beam element with a rectangular cross-section can be achieved by enlarging its width (e.g., increasing the shotcrete thickness). Other cross-sections are modified by directly inputting new (larger) values of the cross-section parameters.
