摘要：Due to the huge computational workload of dynamic computation, engineering and technical personnel tend to apply artificial seismic wave with shorter total time duration,which easily leads to a low efficiency and accuracy of the numerical generation of artificial waves in some cases.To overcome this problem,the matching relationship is analyzed between the main control parameters of ground motion history and the target response spectrum,especially for the effects of ground motion duration on the response spectrum.The basic numerical reasons are analyzed for the failure or low accuracy of traditional artificial wave generation.Based on the above discussion,an initial screening criterion for the long-period spectral values is proposed,and a rapid pre-correcting algorithm using long-period spectral values as control standard is further brought out with detailed algorithm block diagram.Finally,the proposed algorithm is validated by numerical examples,which shows that it effectively improves the accuracy and success rates of the artificial wave fitting technique from the source.
