Multiple External Response Spectra

Currently STAAD.Pro supports the use of an external response spectra that can be used in multiple cases with different damping value, as defined in the help topic TR.32.10.1.1 Custom Response Spectrum Specification. However, this is limited to only support a single external response spectrum definition which is used for all response spectrum cases.

This idea is to extend this offering allowing multiple external spectra to be referenced and used in different load cases.

The benefit:-

Provide designers a method to reuse commonly used spectra definitions from a central location without having to insert all the spectra data into each file.
