Storey Masses

In seismic analysis there is often a need to extract mass and (torsional) inertia data for each storey of a structure. This option looks at the structure, storey by storey, summing the mass and Izz inertia across all the nodes in that storey. The results are output to a csv file which can be opened in Excel.

This dialog can be accessed from the “Model | Seismic | Storey Masses” menu command. In order to use this option the model must contain storeys and there must be at least one dynamic analysis task.

Definition

Analysis Task

A list of dynamic analysis tasks are displayed. The mass calculation is based on the mass specification for the modal analysis (including additional mass).

SI or User Units

Output can either be in SI or the current model units.
