Lanczos向量叠加法的改进及其在高层结构动力分析中的应用

Improvement of Lanczos vector superposition method and its application to dynamic analysis of tall building

本文用柔度法形成高层建筑结构的动力方程，在对现有Ｌａｎｃｚｏｓ向量叠加法改进后，建立了用改进的Ｌａｎｃｚｏｓ向量叠加法进行高层建筑结构动力计算的具体步骤与原则。

In this paper, the deflection method is used to form the dynamic equation, a frequency dependent Lanczos vector superposition method is presented, and the principles and the steps of computing dynamic reactions of tall building are set up by using the modified Lanczos method.
