Refer to 2.4.1 Generated Load Combinations for additional information on generated load combinations. Note that the load combinations generated in this mode are only applied where the special amplified seismic load combinations are referenced in the selected design code. The system over-strength factor (Omega) is required to automatically generate the seismic design load combinations. Omega is based on the building frame type and should be taken from the appropriate building code.

For a structure that contains frames of more than one type (with different omega factors) the engineer will have to repeat the post-processing checks. The omega factor for a single frame type should be used to generate load combinations and the associated frames should be checked. This process should be repeated for each frame type.
