| 摘 要： | 通过对 8根承受双向偏压力、剪力作用的钢筋混凝土柱在低周反复扭矩作用下的抗震性能试验 ,对钢筋混凝土复合受扭构件的破坏形态、滞回曲线、延性及耗能、承载力、刚度及滞回阻尼等特性以及轴压比、相对偏心距对它们的影响进行了分析 .并通过空间变角桁架理论推导出扭矩、轴压力、双向弯矩和双向剪力间的承载力相关公式 ,最后通过相关公式和试验结果拟合出极限扭矩实用计算公式 .分析表明公式计算值与试验值符合较好

| Abstract: | By means of an experiment of eight reinforced concrete (RC) columns subjected to biaxial eccentric compression,shear and low-cyclic torsion,the failure modes,hysteresis loop,ductility,energy dissipation,strength,rigidity and hysteresis damping properties as well as influences of compression level and relative eccentricity on the properties are analyzed.Based on the variable-angle space truss model theory,an axial compression-biaxial bending-biaxial shear-torsion interaction equation is developed and finally a practical formula of ultimate torsion strength is derived.The predictions of the formula agree well with the experiment results. |

| Keywords: | members subjected to biaxial eccentric compression and shear combined torsion hysteretic behavior strength deterioration rigidity deterioration |
