[提要]  高层建筑混凝土结构在竖向荷重及风或地震作用下，其结构稳定己成为设计中需要考虑的问题。结合高层规程(JGJ3 - 91)的修订，分析在风和地震作用下，影响高层建筑混凝土结构的临界荷载的主要参数抗侧刚度与重力荷载比，提出了控制及验算结构稳定的设计建议。可供工程设计时参考。

The stability of tall building under vertical load and lateral load such as wind load and seismic load has to be considered in design. The main factors, the ratio of lateral rigidity to gravity, that affect the stability of tall building concrete structures have been studied, and some suggestions for design are provided.
