大底盘多塔楼结构的整体稳定计算
|
摘要
用沿高度方向分段连续化的方法,对底部为大底盘、上部为多塔楼的高层建筑结构建立了整体的稳定方程,用常微分方程求解器COLSYS求解,为这种复杂的高层建筑结构的整体稳定计算提供了一种简化算法.
A piecewise continuous model is taken as the computational model for the overall stability analysis of multi-tower-building structures with enlarged base at the bottom. The stability differential equations for the model are derived. Moreover, the critical loads and the corresponding buckling modes are determined numerically by means of the ODE(Ordinary Differential Equation) Solver, which is a program developed for solving various ODEs, including eigenvalue problems.
