| 摘 要： | 利用拟静力试验对钢筋混凝土框架柱分别进行了不同轴压比下单，双向循环加载和双向变轴力循环加载，得到了在不同加载路径和加载方式下力与位移关系的本构模型，通过比较不同加载形式下柱的破坏形态，破坏程度，对试验现象和滞回曲线的分析得出：双向荷载作用使得柱的承载力较单向荷载作用有较大的下降，在双向荷载作用下，构件的强度退化和刚度退化现象均较单向荷载作用下严重得多，且轴压比的增大加重了构件的强度退化和刚度退化现象，双向荷载作用使得柱的延性也大为降低。

| Abstract: | Quasi static experiments of reinforced concrete frame columns are carried out under different axial compressions and uniaxial/biaxial cyclic lateral loading. The relationship between force and displacement is obtained with different loading paths and different loading approaches. Through the experiments and analyses, it can be concluded that the bearing capacity of columns under biaxial lateral load is lower than uniaxial lateral load, and degradations of strength and stiffness are also more serious. This kind of phenomenon is aggravated with increase of the axial compression ratio. At the same time, the ductility of column under biaxial lateral load is also reduced. |
