https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/204098/seismic-shear-force-applied-in-center-of-gravityGood Day Everyone I do have a quick question regarding Seismic Load. Q1. If I have the total mass for seismic design as Force (kN), then I apply it to center of mass/gravity of my structure, How can I transfer it to the nodes in the structure?

I&#39;m not sure if I am asking this correctly, please correct me if I&#39;m wrong.&nbsp;</p> <p>Thank you again.</p><div style="clear:both;"></div>https://communities.bentley.com/thread/612680?ContentTypeID=1Tue, 06 Oct 2020 00:33:51 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:6c42a60d-84d3-4b6a-8d9e-5623fc48ef41Sye<p>Yes you can use master slave.</p> <p>There are training videos available on the Bentley Learn Server which explains generation of&nbsp;seismic loads. There is a whole section on Response Spectrum Analysis which should be useful for you<br /><a href="https://learn.bentley.com/app/Public/ViewLearningPathDetails?lpId=111709">https://learn.bentley.com/app/Public/ViewLearningPathDetails?lpId=111709</a></p><div style="clear:both;"></div>
