摘要(Abstract):

为深入认识钢筋混凝土框架柱轴压比限值的含义 ,从框架柱的破坏机理、配箍构造等因素出发 ,引伸建立轴压比与变形角、配箍特征值的关系式 ,以便更好理解新修订的《混凝土结构设计规范》(GB5 0 0 1 0— 2 0 0 2 )的具体规定。另外 ,提出高强螺旋箍筋能增加框架柱抗震性能 ,是解决框架柱轴压比问题的有效措施 ,其研究结果对发展应用高强混凝土有实际意义
In order to understand the limited value of axial compression ratio of RC frame column of the revised code of RC structure,the article found the relationship between axial compression ratio and deformable angle and characteristic value of stirrups by analysis of destroyed mechanics and stirrup construction of frame columns.In addition,we draw the conclusion that the high strength stirrup can be used to improve the anti earthquake behavior of the frame columns,which also will extend the limitation of axial compression ratio.
