How does ETABS determine mass for calculation of auto-earthquake loads and dynamic analysis?
The default setting is to use Self & Specified Mass. Self mass is calculated for objects based on the Mass per Unit Volume defined in the material properties, and specified masses are any additional masses assigned by the user. An option also exists to define mass from loads, which converts factored load cases into mass.
