ST7-1.50.60.8 Using Links to Model Rigid Diaphragms
Certain structural members can be modelled as having infinite in-plane stiffness, and zero out-of-plane stiffness. This is typically done in the analysis of buildings, in which the floors are assumed to act in this way during seismic events. To achieve this, Strand7 provides a special type of planar rigid link cluster, in which the plane with infinite stiffness is specified by the user.  A simple example is developed in which the floors of the six storey building from ST7-1.40.35.22 AS 1170.4-2007...
