【摘要】 目前求解性态点处位移的方法均为图形方法,而且多数需迭代才能完成。本文提出一种求解性态点处位移的数值方法。并将本文方法与能力谱法求出的位移值进行比较。比较结果说明本文所提方法不但正确而且求法简单。更多还原

【Abstract】 The current used methods, such as capacity spectrum method, for determining performance point are approaches graphically, and most of them need iteration. The paper presents a numerical method for determining performance point without any iteration. Displacements at performance point from both the numerical method and capacity spectrum method are compared. It indicates that the current numerical method is not only more accurate in precision but also simple in calculation than the currently used ones.更多还原
