The Conditional Mean Spectrum Based on Eta Indicator

ground motion record GMR selection is an important issue in the structural seismic response history analysis for this purpose a set of GMRs with specific properties should be selsected the code -based approaches propose to select a set of records which shall be compatible with a target spectrum e.g uniform hazard spectrum UHS many research results have shown that using the UHS leads to significants bias in the structural response assessment.
