AD.2007-09.2.3 Check for Soft Story

The CHECK SOFT STORY option may added to a FLOOR DIAPHRAGM command set to check for soft stories per either IS1893:2002 or ASCE7-95 codes.

Additionally, the story stiffnesses used in calculating story drift or checking soft stories can be added to STAAD.Pro output by including the command PRINT STORY STIFFNESS in the post analysis print commands section.
