| 摘 要： | 采用有限分割有限元，应用Ｎｅｗｍａｒｋ法与Ｎｅｗｔｏｎ－Ｒａｐｈｓｏｎ法相结合的方法对具有几何非线性、物理非线性的流动方程进行了逐步积分，求得高层钢结构地震动力反应，以便对高层钢结构弹塑性状态下的内力和变形进行验算。不仅推导了有产理论公式，还编制了有限元计算程序。通过多个算例验证了该方法的正确性与实用性。

| Abstract: | Using finite-segment finite element method, and Newmark method, and Newton-Raphson method, the dynamic equation with geometrically and material nonfinear problems is integrated step by step to get the earthquake dynamic response of high-rise steel structure and carry on the elastic-plastic intemal force and deformation checking computation of high- rise steel structure. The relative theoretic formulas are derived and the finite-element calculation program is worked out. Several calculation examples have demonstrated that the method used in this paper is correct and practical. |
