My team is wondering if instead of entering 30 for the number of records collected in the PEER tool (number used in the guide provided), we can directly put 11 directly on the tool, and put these in the proposal with their respective graph. And another question would be if we should scale them with their respective scale factor before placing them in the proposal.

Question

Accepted Answer

1.) You can put 11 ground motions in the platform. However, usually one would ask the platform for a bigger number and then choose the best 11 based on engineering judgement.
2.) A Figure including the scaled response spectra at the target level and the target spectrum is recommended.
