Using the Criteria - General command, the user can declare whether the effects of the rigid end zones will be considered or ignored. If the effects are to be included in the analysis, a percent reduction can be entered.

A value of 0.0 indicates that the rigid end zones are not to be reduced, and their full effect is to be considered, (i.e., the full panel zone is rigid). See "Technical Notes" for a discussion of the rigid end zone.

Making changes to the Rigid End Zone criteria after a model has been analyzed necessitates a re-analysis of the structure.
