摘要
地震作用于高层建筑基底 ,传至上部有时滞。通过计算不同时滞下结构的时程反应 ,说明在高层建筑中必须考虑时滞问题。根据地震波速确定时滞 ,再由此算得的顶层放大系数与振动台试验吻合很好。
The time delay phenomena will always appear unavoidably when the high rise structure is subjected to the earthquake stimulation.In this paper,the reason and the essence of the time delay phenomena are discussed.Through calculating the different responses of the structure with the different time delay,we can see that the time delay is necessary to consider in the time history analysis of the structure system.And what's more,the analytic result with the time delay which is calculated from the earthquak wave velocity is conincidental with the shaking table test result very well.
