摘要
随机振动理论是分析和研究地震作用最为有效的方法，但由于其计算方法复杂低效，而未被实际工程设计所采用。虚拟激励法很好的解决了这个问题，为功率谱法在工程设计中的应用开辟了广阔的前景。本文采用虚拟激励法对某层间隔震结构进行了抗震验算，并与时程分析法的计算结果进行了比较，得到了一致的结果。证明了计算方法的有效性，并为其他类似工程的抗震设计和分析提供了借鉴和帮助。
Abstract
Random vibration theory is the most effective wayto analysis seismic action. However it is not adopted in practicalengineering design because its calculation method is complex andinefficient。Pseudo Excitation Method can solve this problem welland broaden the prospect on applying power spectrum method inengineering design. In this paper, the pseudo-excitation method isadopted to a Interlayer Seismic Isolation structure in seismic checking.The results obtained from this method are similar to that from timehistory analysis method. The study proves the validity of this calculationmethod, and it serves as a reference for design of similar projects.
