What to check when using 'Dynamics'

Dynamics

When the functionality 'Dynamics' has been activated, the following limitations should be taken into account.

The following limitations have been tested on Scia Engineer 2012

Calculation

  • Modal analysis is fundamentally elastic linear. The only exception is 2nd order effects. Second order can be taken into account in modal analysis, either by means of initial stresses or using sequential analysis.
  • Seismic loading cannot be calculated in a nonlinear way, but they can be combined with nonlinear results: in a linear or envelope combination which contains a seismic load case, it is possible to combine it with a nonlinear combination.
  • Seismic load cases cannot be used in a nonlinear combination.
