Equivalent Linear Method

The Equivalent Linear Method is a common way used in earthquake engineering to analyze nonlinear site seismic response, but the response under strong motion is underestimated by the way. For analyzing nonlinear response more veritably, in the study, a time-domain nonlinear analysis method was proposed and used in a case for 1D seismic response analysis of soil layers under strong motion. The results obviously showed that, comparing with true nonlinear method, the Equivalent Linear Method underestimated in the case in natural period range of common civil engineering structures. The true nonlinear method adopted in the study is more fitful for nonlinear response of soil layers under strong motion.
