高层建筑结构分析的有限元──有限条混合方法

The Mixing Method of Finite Element & Finite Strip in the Structural Analysis of Tall Buildings

在高层建筑结构分析中将有限元与有限条方法结合起来，用三次B样条函数的线性组合作为位移函数，并构造了广义有限杆单元，解决了有限元有限条混合单元的连接问题，可以进行框架─-剪力墙及框支剪力墙等的分析。编制了专用计算程序。工程实例计算表明：计算结果与现有的试验结果吻合较好，计算精度是令人满意的，具有工程实用价值。

In this paper, the author joined author finite method with finite strip method in the structural analysis of tall buildings, used linear combination of cubic function of B sample strip as displacement function, constructed generalized unit of finite element and finite strip. It overcame the defects of finite element and finite strip method themselves. Specilized calculation procedure was used in the practical work.
