高层建筑结构考虑扭转简化分析的超元法

Super Element Method for Simplied Analysis of Tall building Considering Torsion

提出高层建筑结构考虑扭转简化分析的超元法,将纵横向各片抗侧力结构均简化处理成一根等效柱。空间协同分析时,采用超元法(每个单元由多根杆组成)计算等效柱的侧移刚度矩阵,自由度成倍减少。不论是框架、框剪结构还是剪力墙结构,计算侧移刚度矩阵、内力和位移时,都具有统一算式,计算简便。

The super element method for simplied analysis of tall building considering torsion is presented.The method is applied to calculate lateral stiffness matrix in space cooperating analysis and the the degree of freedom can be greatly decreased.In addition,the lateral stiffness matrix,internal forces and displacement have the unified formula for the frame,frame-shear wall structure as well as shear wall structure.The method is simple and reasonable in calculation and programming.
