摘要
介绍了结构抗震的三维反应谱分析法,并通过具体算例与国外的“百分法组合法则”相比较,得出三维反应谱法的准确性和弊端,最后分析讨论了中国规范对三维反应谱法的改进效果。
Three-dimensional response spectrum method in seismic analysis are introduced,reveals the accuracy and drawbacks by comparing it with American "100/30 Rule" through a special example.In addition,the paper discusses the effect of improving the response spectrum method by Chinese codes.
