| 摘 要： | 为了对高层建筑结构进行抗震优化分析，提出考虑变刚度的高层建筑结构空间协同分析简化方法.利用等效柱模型，以楼层划分单元，对结构进行分析，每个结点只有2个自由度.采用该方法可使整个结构自由度大大减少，并适用于刚度多阶变化的情况.用该文的方法分析变刚度高层结构简便、合理，并能用于实际工程.

| Abstract: | To analyze tall structures with aseismic optimal, we present a mutual affection analysis of tall structures with variable stiffness. Using the equivalent column model, the whole structure is divided into levels. There are only two degrees of freedom. So analysis of tall structures is simplified. Using this method, the freedoms of degrees of the whole structure are greatly reduced. The method can be applies to analysis of tall structures with variable stiffness. Themethod is simple and reasonable. |
