WebJun 20, 2024 · As we know, earthquake acts on a structure laterally, and diaphragm is used to transfer lateral forces to vertical members. We need to assign the proper diaphragm to the slab. Proper means the diaphragm which can distribute the forces to vertical members as well as it transfer the forces through slab. WebOct 23, 2024 · ANSWER: To retrieve membrane forces which occur in-plane to semi-rigid diaphragms when user-defined seismic loads are applied to a structure, loads may be directly applied either to floors as distributed loads, or at discrete points according to seismic mass distribution.
