摘　　要：对与设计及施工关系较密切的钢骨混凝土柱的最小体积配箍率进行探讨,讨论相关规范、规程中规定的差异,给出若干实际工程设计的钢骨混凝土柱的体积配箍率。基于极限分析理论,探索混凝土柱的极限破坏机制,建立了极限平衡方程并求解出最小体积配箍率。The minimum volume stirrup ratio of steel reinforce concrete（SRC） columns was discussed,which has be used widely in design and construction.Different provisions in relevant codes were discussed,while volume stirrup ratio of SRC columns in some projects were provided.Based on the limit analysis theory,ultimate failure mechanism of concrete columns was explored,limit equilibrium equation was established and the minimum stirrup ratio was solved.

关 键 词：钢骨混凝土柱 体积配箍率 极限分析
