The "Earthquake"serves to input earthquake parameters. Directions of input earthquake effects are displayed on the desktop.
If not provided by measurements the coefficients kh and kv can be calculated following the approach adopted from .
Analysis of foundation bearing capacity while accounting for earthquake is described in the theoretical part of the help, chapter "".
During seismic analysis, the program performs the calculation of bearing capacity for both cases - with and without seismic effect. The resultant bearing capacity is lower from these two values.
Note: The frame is accessible only in the case, when analysis for drained conditions is selected in the "" frame.
