等效杆系模型在核心筒分析中的应用

Equivalent member system models and their application to calculation of core tube structures

以分析剪力墙结构的等效杆系模型为基础 ,对核心筒进行了线性分析 ;推导了 4种等效杆系模型的统一单刚形式 ,并作出对比 ;对楼板提出简化计算模式 ,保证各筒壁间转角位移协调 ;编制了电算程序 ,算例表明 ,采用墙板单元分析核心筒结构计算量小。

Equivalent member system models,which are linear models mainly applied to analyze shear walls,are used to analyze core structures in this paper.The integrated element stiffness matrices of four equivalent member system models are derived and comparison of the matrices is given.To coordinate the rotation displacement of each wall of core tubes with each other's,the simplified calculation model of slabs is developed.Microcomputer based programs are compiled.It is proved that wall panel element is more efficient and more accurate to analyze core tube structures.
