Story Diaphragm Group for Construction Stage

At the time of construction stage analysis for a high-rise building, the story diaphragm information that is automatically defined by the Story function is assigned to appropriate boundary groups. These boundary groups must be created by the Define Boundary Group function prior to being assigned the story diaphragm information. When Construction Stage Wizard is used, the boundary group

s are automatically generated and assigned to each story. Each boundary group becomes activated in the corresponding construction stage at the time when the dead (slab self-weight) load starts exerting on the story.

From the Main Menu select Boundary > Etc. > Story Diaphragm Group for Construction Stage.
