摘要
建立了用改进的Ritz向量叠加法计算高层结构非线性地震反应的计算原则与步骤,通过与常规直接积分法的比较研究,验证了本文方法的高效性与可行性.
The calculation principles and the calculation steps of nonlinear seismic response analysis of tall building structures by using the modified Ritz vectors superposition method have been set up,the comparsion between the proposed method and the common direct integrate method is made by numerical examples,the effectivelity and possibility of the proposed method is presented.
