Dear Seismosoft,

How can I obtain the total weight of the structure and also the amplitude of mode 1 at each level?

You can obtain such information in the Post-Processor module. Do read the Help System and/or User Manual.

Please, can you be more precise?
I tried using the Post-Processor module, but no result. Before asking I read the Help System, Verification report, User Manual and all topics of this forum. As you already know, many have asked the same thing and got the same response: to use the Help System and/or User Manual.

I imagine there are multiple ways to get what you need scorpio85. Try this:

After extracting the modes in the Processor module, proceed to the Post-Processor.

You will initially be, most likely, in the Deformed Shape Viewer tab. You can animate each mode here.

To get the amplitude at each node, simply select the Step Output tab in the Post-Processor.

To get the structure mass, you may select the Modal/Mass Quantities tab, still in the Post-Processor. Once you have entered the Modal/Mass Quantities tab, you could select the Nodal Mass tab.

One way to get the structure mass would be to right-click on the Nodal Mass tabular data, choose Select All, then choose Copy Selection. I then open Excel and Paste the tabular data into a blank worksheet. I can then quickly use the sum function in Excel to get the total masses and rotary inertias in each DOF. And then using the appropriate multiplier, I can convert the masses to weigts.

There are probably easier ways, but this seems to work quite well and it is quite easy.

Best of luck scorpio85.

Thanks a lot huffte.
