| 摘 要： | 分析了影响钢筋混凝土框架柱延性的主要因素,指出框架柱延性主要与轴压比和箍筋对混凝土的约束程度有关,并结合《建筑抗震设计规范》（GB50010-2010）介绍了保证框架柱延性的主要抗震构造措施：轴压比限值、最小配箍特征值及纵向钢筋最小配筋率.

| Abstract: | This paper analyzes the main factors which influence the ductility of RC column,and it indicates the ductility of RC column is mainly related to the axial compression ratio and the confinement from stirrups.Combined with Code for Seismic Design of Buildings(GB50010-2010),the main measures to insure the ductility of RC columns are introduced as: the limit value of axial compression ratio,the eigenvalue of minimum stirrup ratio,and the minimum longitudinal steel ratio. |
