摘　　要：将QR法与Pushover分析方法相结合,提出了高层建筑结构静力弹塑性分析的Pushover-QR(PO-QR)法。该方法沿用了常规Pushover方法进行抗震结构静力弹塑性分析的实施思路,用QR法代替Pushover分析方法中的有限元部分,充分利用这两种方法的优点,使得抗震结构静力弹塑性分析的计算得到较大的简化。PO-QR法程序的工程算例表明,该法是一种经济、有效、可行的分析方法。Combining the QR-method and the Pushover analysis method together, the authors put forward the Pushover-QR method for static elasto-plastic analysis of high-rise buildings in this paper. The Pushover-QR method still continues to use the ideology of regular Pushover method in static elasto-plastic analysis of the structures. By replacing the part of finite element in the Pushover analysis with the QR-method and by making full use of the advantages of both the QR-method and the Pushover method, the Pushover-QR method largely simplifies the calculation of the static elasto-plastic analysis of the structures. The Pushover-QR method is applied to calculate some examples, which show that the Pushover-QR method is an economic, efficient and feasible analysis method in the static elasto plastic unalysis of the structures.
