本文提出了广义位移的有限条方法,用于分析物理特性沿高度突变的高层建筑构。该法消除了经典有限条方法分析此类结构的缺陷,即截面应力在刚度突变处不连续,致使靠近突变截面一定范围内的应力收敛到不正确的结果。本文对这种非均匀的高层建筑平面结构在T-300微型机上进行了实例分析,算例包括实体剪力墙、联肢墙、框剪结构。此法同样适用于分析均匀高层结构。
In this paper, a finite strip method for generalized displacements is proposed to analyze high-rise building structures with highly mutated physical properties. This method eliminates the flaws of the classical finite strip method for analyzing such structures, that is, the cross-sectional stress is discontinuous at the point where the stiffness changes, resulting in convergence of the stress in a certain range near the abrupt section to an incorrect result. In this paper, the non-uniform high-rise building plane structure is analyzed on the T-300 microcomputer. Examples include physical shear wall, joint wall, frame shear structure. This method is also suitable for analyzing uniform high-rise structures.
