摘要

本文用沿高度方向分段连续化的方法,对沿高度方向为阶形(二阶或多阶)变截面,在平面内为任意斜向布置的框架-剪力墙-薄壁筒协同工作体系,建立了整体的稳定方程.用常微分方程求解器(COLSYS)求解.对复杂的高层建筑结构的整体稳定计算,提供了一个简单可行的算法.
In this paper, a piecewise continuous model is taken as the computational model for the overall stability analysis of tall stepped building with frame-shear wall-thin walled core skewly combined structure.The stability differential equations for the model are derived. Moreover, the critical load and the corresponding buckling mode are determined numerically by means of the ODE (Ordinary Differential Equation) Solver, which is a program developed for solving various ODEs, including eigenvalue problems.
