Evaluation of Modal Combination Methods for Seismic Response Spectrum Analysis
Evaluation of Modal Combination Methods for Seismic Response Spectrum Analysis Regulatory Guide 1.92 ''Combining Modal Responses and Spatial Components in Seismic Response Analysis'' was last revised in 1976. The objective of this project was to re-evaluate the current regulatory guidance for combining modal responses in response spectrum analysis, evaluate recent technical developments, and recommend revisions to the regulatory guidance. This paper describes the qualitative evaluation of modal response combination methods.
