为了计算在各种静动荷载以及单向,双向地震作用下复杂体形高层建筑非线性反应,本文提出了一种组合结构计算模型和算法。按本文方法研制了通用的计算机程序,利用这个程序可作常规的静动力分析,完成结构各部件的截面设计。然后根据实配钢筋,进行弹性或弹塑性动力分析。进行弹塑性动力分析时对于各类不同的单元,提供了不同的屈服准则。程序也适用于求解地基、基础与上部结构共同作用的动力反应问题。文中给出了实际工程算例。
In order to calculate the nonlinear responses of complex tall buildings under various static and dynamic loads as well as one-way and two-way earthquakes, this paper proposes a combined structure calculation model and algorithm. A general computer program has been developed according to the method of this paper. This program can be used for routine static and dynamic analysis to complete the cross-section design of the components of the structure. Then according to the actual rebar, elastic or elasto-plastic dynamic analysis is performed. Elasto-plastic dynamic analysis provides different yield criteria for different types of units. The procedure is also suitable for solving the dynamic response problem of foundations, foundations and superstructures. The actual engineering example is given in the article.
