摘要
提出了纯框架结构按照整层有侧移失稳模式进行框架柱稳定性计算的完整方法,并给出其解说.提出了层长细比的概念并给出了计算公式,根据层长细比,计算层稳定系数,然后用于基于层整体有侧移失稳的框架柱平面内稳定性计算公式.对于平面外稳定计算,考虑了平面外是有侧移失稳和无侧移失稳两种情况,分别给出了公式.对双向弯曲的柱子也分各种情况给出了计算公式.
This paper presented a story-based stability design approach of frames,story-based slenderness is proposed and the stability coefficient is than based on the well-known column curves. A story-based in-plane stability design formula of columns is proposed. For the out-of-plane stability, design formulae are also proposed for sway buckling and non-sway buckling in the out-of-plane. For columns biaxially loaded, design equations are also given.
