摘要
文献［１］采用的改进Ｐ－△法已对３６榀１０层３跨刚架计算了荷载－位移的关系曲线，根据以上资料对支撑的作用、刚架的延性和屈服强度比以及刚架层间相对位移进行了分析讨论，并对支撑设计提出了若干探讨．
ten storey and three span frames were calculated in Ref.[1] by using the improved P-△methods,and the load- displacement curves were obtained.Based on these results,the of feets of the bracing on the ductility,the yielding-ultimate strength ratio and the drifts of the frames are discussed,andsome suggestions for the design of bracings are proposed.
