| 摘 要： | 对不同锈蚀程度的钢筋混凝土圆柱进行低周反复试验,研究了不同轴压比下的钢筋锈蚀率对钢筋混凝土圆柱滞回曲线、骨架曲线、刚度、延性及耗能能力的影响;给出了试件累积耗能、屈服荷栽、极限荷栽、荷栽最大值和位移延性系数与钢筋锈蚀率和轴压比的关系.研究表明,随着钢筋锈蚀率和轴压比的增大,试件的滞回曲线趋于干瘪,骨架曲线下降段变陡,试...

| Abstract: | A low-frequency cyclic horizontal loading test was conducted on circular reinforced concrete(RC) columns with different degrees of rebar corrosion.In the experiment,the seismic behavior of corroded circular RC columns under different axial loads,such as hysteresis loops,skeleton curves,stiffness,ductility and dissipating energy capacity,were studied,and the relationships between the seismic behavior,such as accumulated energy dissipation,yield load,ultimate load,maximum load,displacement ductility coefficie... |
