| 摘 要： | 本文用有限条元方法求解高层筒体结构的整体稳定及二阶位移分析。先把实际框筒结构连续化为正交各向异性折板结构,用有限条元离散化,在竖向采用了有良好性能的B样条函数。用最小势能原理建立稳定及二阶位移分析方程。可用于高层筒体结构及剪力墙结构等的空间稳定及二阶位移分析。

| Abstract: | In this paper, overall stability and second-order displacement analysis of tall building tubular structures by use of the* Finite Strip Method arc presented. The framed tubes are firstly replaced by equivalent orthotropic continua. Then the equivalent continua are analyzed by applying F.S.M. in which B spline function for interpolation in vertical direction is used. The Minimum Potential Energy Principle is used to set up the equations of stability and second-order displacement analysis. |
