摘要
本文对需要考虑楼板变形的变截面框架-剪力墙结构的整体稳定问题建立一个连续化的并联模型,导出其稳定问题的微分方程组,用常微分方程求解器求解其临界荷载和相应的失稳形态。
In this paper, a continuous parallel model is taken as the computation mo-del for the overall stability analysis of tall frame-shear wall structures withvaried sections, considering the floor slab deformation by use of the piecewisecontinuum technique. Then, the stability differential equations for the modelare derived. Moreover, the critical loads and the corresponding bulking modes are de-termined numerically by means of the ODE (Ordinary Differential Equation )Solver, which is a program developed for solving various ODE's, includingeigenvalue problems.
