Random Response Analysis using two sets of PSDs

Hiroshi Aoyama

 Hello everyone,

I want to apply two sets of PSD to two nodes of the model.

For example, PSD1 table is applied to node1, and PSD2 table is applied to node2. 

I don't understand in the RANDPS load collector what are the J and K input. It is said in the User Guide that there is a excited load and an applied load? How can they be different, what does that mean?

Thank you for your help.

You will use different J and K when you need to input the Cross-PSDs in your model.
