【摘要】：用取代率為85%再生粗骨料制作3個(gè)再生骨料混凝土空心砌塊墻體試件RACHBW,在不同豎向荷載作用下對(duì)RACHBW試件進(jìn)行水平低周往復(fù)加載,通過(guò)試驗(yàn)研究分析RACHBW試件的承載能力、破壞過(guò)程及破壞特征,并從滯回特性、骨架曲線、延性、耗能能力等方面分析了其抗震性能。試驗(yàn)結(jié)果表明:RACHBW試件在水平低周反復(fù)荷載作用下的破壞過(guò)程與天然骨料混凝土空心砌塊墻體(NCHBW)相似,RACHBW試件滯回曲線飽滿,延性較好,具有良好的抗震性能,可望在實(shí)際工程應(yīng)用中大力推廣。
[Abstract]:Three recycled aggregate concrete hollow block wall specimens were made from 85% recycled coarse aggregate. Under different vertical loads, RACHBW specimens were subjected to horizontal low-cycle reciprocating loading. The load-carrying capacity of RACHBW specimens was analyzed through experimental research. The failure process and failure characteristics are analyzed from hysteretic characteristics, skeleton curves, ductility, energy dissipation capacity and so on. The test results show that the failure process of the specimen under horizontal low cycle cyclic loading is similar to that of the natural aggregate concrete hollow block wall (NCHBW). The hysteresis curve of the specimen is full, the ductility is good, and the specimen has good seismic performance. It is expected to be popularized in practical engineering application.
