摘要
在钢筋砼杠架结构中加入偏心支撑,提高了结构的抗侧刚度,改善了结构的承载能力和耗能能力。对偏心支撑钢筋砼框架结构的耗能梁进行了弹塑性静力分析,提出了它由延性破坏到脆性破坏的分界线;得出了它在弹性阶段及弹塑性阶段的内力分布情况;并采用砼劈裂强度计算模型,推导了它的抗剪强度计算公式,计算结果与实际破坏情况符合较好。
Adding the eccentricaal brace to the R.C. frames is for strengthening the side stiffness and improving the loadbearing and energy-consuming ability.In this paper,the active beam links in eccentrically braces R.C.frames(EBF) is analyzed in the static state of elasticplastic,and the boundary between ductility and brittleness destruction is put forward,and stress distribution in the state of elastic-plastis is founded;shear strength which adopts the computing model of split strength is formulated,and the theoretical and experimental results are in good agreement.
