Structure Mass for Rigid Diaphragm Modelling
When calculating the Structure Mass; structural geometry, element section sizes and external loads present in the structure are taken into consideration.
In the example below, the Structure Mass Calculation will be made in a project where a rigid diaphragm is accepted.
