Masses

The Mass tab contains functions, that are necessary for dynamic calculations. Mass cases and mass combinations can be created for masses that were placed on the model manually or converted automatically from loads into masses.

📄️ Mass cases and mass groups

Masses on the structure, just like in the case of loads, has to be grouped together in mass cases and mass groups. Before defining masses on the structure, groups and cases should be defined with using the Create mass cases and mass groups () function.

📄️ Definition of mass combinations

Definition of mass combinations works like the load combination definition (Chapter 6.3), but without the possibility to generate mass combinations automatically. Factors for each mass case have to be set manually to create a mass combination.

📄️ Creating point masses

Point mass() objects can be placed at any point of the structure. Every placed point load will be automatically assigned to the active mass case of the mass case dropdown menu.

📄️ Creating response spectrums

With the Create response spectrum() function, two types of response spectrums can be defined:
