| 摘 要： | 用取代率为85%再生粗骨料制作3个再生骨料混凝土空心砌块墙体试件RACHBW,在不同竖向荷载作用下对RACHBW试件进行水平低周往复加载,通过试验研究分析RACHBW试件的承载能力、破坏过程及破坏特征,并从滞回特性、骨架曲线、延性、耗能能力等方面分析了其抗震性能。试验结果表明:RACHBW试件在水平低周反复荷载作用下的破坏过程与天然骨料混凝土空心砌块墙体(NCHBW)相似,RACHBW试件滞回曲线饱满,延性较好,具有良好的抗震性能,可望在实际工程应用中大力推广。

| Abstract: | Under different vertical loads,the low-cycle reversed loading test of 3 pieces of recycled aggregate concrete hollow block walls RACHBW specimens with 85% recycled coarse aggregate's replacement ratio was conducted in this research. The load carrying capacity,damage process,failure characteristics of RACHBW were studied,and also the seismic behaviors, such as hysteretic characteristics, skeleton curve, ductility and ability of energy dissipation,were analyzed. The research result indicates that in the damage process of the low-cycle reversed load,RACHBW specimens are similar with natural concrete hollow block walls NCHBW specimens. and that the RACHBW specimens has plump hysteresis curves, good ductility, strong energy dissipation capacity and good seismic performance. The conclusion is that this material can be used in real engineering structure. |
