摘要
揭示了Ｒｉｔｚ向量叠加法的实质及存在的问题，发展了与外载频率相关的Ｒｉｔｚ向量叠加法及多维外载作用时的Ｒｉｔｚ向量叠加法．着重讨论了地震荷载作用下，用Ｒｉｔｚ向量叠加法进行结构反应计算的有效性及局限性．
The essence and the existing problem of Ritz vector superposition method is revealed,and a frequency dependent Ritz vector superposition method under the external foods of one dimension and multiple dimension is presented. The emphases are put on the discussion of feasility and limitation of structural seismic reaction analysis by using the Ritz vector superposition method.
