I have a model of a building in which I have already defined the structural and non-structural masses. Structural masses are defined through the density of the material while the non-structural masses are defined as point masses. In this step, I want to perform the modal analysis. In the subsequent steps, I want to define a static analysis and later a dynamic analysis(earthquake). During the static analysis, I want to exploit the gravity load for the structural mass while I want to use distributed pressure for the non-structural. But if don’t remove the point masses I would consider it twice. In the subsequent step, I need these masses for the dynamic analysis. To resume, I have to apply the point masses in the first step, remove from the second, and put in the third. Is it possible? When I try to do this from one step it’s immediately eliminated from all the steps.

Greetings,

You cannot activate and deactivate mass in any step. In other words, either you define mass or not for the whole analysis. But it’s different when it comes to the Gravity load. You can activate or deactivate the gravity load through the load manager dialog box in any step you want.

I hope this will help you.

Best wishes.
