摘要: Long-period ground motion has become an important consideration because of the increasing number large and long-period structures. Therefore, a thorough investigation on formation characteristics is desirable for engineering applications. In this work, analytical study performed to examine effect several parameters combining mode equivalent harmonic components dynamic response systems. The results work show that in are evidently influenced by intensity rise time, duration, phase mode. Moreover, motions simplified simulated separate through proper combination. findings believed be useful selection input structural seismic analysis.
