depending on their flexibility and their location in the structure. Diaphragms that cannot be classified as either flexible or rigid are referred to as semirigid. The flexibility of a diaphragm affects the distribution of lateral forces to the vertical components of the lateral force-resisting elements in a structure.
236:
The two primary types of the diaphragm are flexible and rigid. Flexible diaphragms resist lateral forces depending on the tributary area, irrespective of the flexibility of the members to they are transferring force to. On the other hand, rigid diaphragms transfer load to frames or shear walls
