Dynamic analysis: Earthquake : Spectrum load cases query

Dear All,

This query is regarding defination of the spectrum load cases.

I wanted to define the spectrum load in some portion of the system.

In the above case, is it necessary to define the anchor movement as Zero?

If your spectrum definition does not include all boundaries (restraints), then the Anchor Movement column is active. If you do NOT enter data here, C2 will calculate it for you. But the calculated value is based on your shock data which may be incomplete for this purpose.
