摘要
高层建筑钢结构在竖向荷载及风荷载或地震作用下,其结构稳定已成为设计中需要考虑的问题。结构的侧向刚度与重力荷载之比即刚重比,是反映结构整体稳定性的关键参数。提出了高层建筑钢结构整体稳定验算的设计建议,可供工程设计时参考。
The stability of steel structure in tall building under vertical load and lateral load such as wind load and seismic load has to be considered in design. The rigidity-gravity ratio of structures is defined as the ratio of lateral stiffness to gravity,which is a key parameter to the overall stability of structures. The stability of steel structure in tall building has been studied,and some suggestions for design are provided.
