Part 5 - Problem 03: When populating the section on the spreadsheet designated for the PEER database ground motion, the discrepancy in the scales of the period between the seed motions and the PEER motion causes the values of the Geomean to populate incorrectly. In this case are we to input the PSA values according to the period values given for the seed motions or remove these values from the Geomean altogether?

Question

Accepted Answer

Yes, we did not foresee this issue with the geomean. Please use the period range provided by PEER for the response spectrum only. Still provide a plot with your scaled geomean using only the four provided seed motions.
