本文利用现有的国内外计算和实测结果,比较了弹性体系地震反应振型遇合的各种现有方法,最后建议采用以各振型最大反应平方和的平方根作为最大总反应。 文中从地震力的统计理论的观点探讨了此法的理论根据;又从现有的计算和实测结果证明此法比其他方法具有更好的精确度。
In this paper, the existing domestic and international calculations and actual measurement results are used to compare the various existing methods for the seismic response of the elastic system. Finally, the square root of the square sum of the maximum response of the vibration modes is recommended as the maximum total response. This paper discusses the theoretical basis of this method from the perspective of the statistical theory of seismic forces. It also proves that this method has better accuracy than other methods from the existing calculations and actual measurement results.
