Second - order elastic analysis of sway frames 有侧移框架二阶效应的弹性分析
Frame with sidesway 有侧移框架12
Research the hinged column from same end moments and different end moments . research the frame column from no sway frame column and sway frame column . the paper use model of variety of stiffness divided into five parts , and consider into all sorts of factors 从等偏心距铰支柱和不等偏心距铰支柱两方面分析铰支柱,框架柱则分成无侧移框架柱和有侧移框架柱两种形式进行分析。
When the lateral stiffness of a bracing system is equal to or greater than five times that of the frame itself , the frame is regarded as a non - sway type , otherwise the frame is classified as a sway type , even if a bracing system is present in the whole structure 区分准则是支撑体系的抗侧刚度等于或大于框架本身抗侧刚度的5倍时,框架看成是无侧移框架。而对于框架无支撑或支撑刚度没有达到5倍框架抗侧刚度的情况,框架归入有侧移框架一类。
