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.

Dialog window "Adjust beam properties" - beam strengthening
