| 摘 要： | 通过对3片不同竖向荷载作用下的再生混凝土空心砌块墙体进行水平低周反复荷载试验,考察了墙体的受力性能、破坏机理及承载能力,分析了其滞回特性、骨架曲线、延性、耗能等抗震性能.研究结果表明:再生混凝土空心砌块墙体在无竖向荷载的情况下,破坏时的裂缝数量较少,主裂缝明显;在施加竖向荷载的情况下,破坏时无明显主裂缝,结构受力均匀.墙体的滞回曲线较饱满,延性较好,耗能能力较强,抗震性能良好.试验墙体的刚度退化趋势大致相同,墙体的初始刚度较大,开裂后刚度退化迅速.

| Abstract: | The low-cycle reversed loading tests of 3 pieces of recycled concrete hollow block masonry walls under different vertical loads are conducted.The mechanical behaviors,failure mechanism,and loading capacity of the walls are studied.The seismic behaviors,such as hysteretic characteristics,skeleton curve,ductility and energy,are also analyzed.The experimental results show that recycled concrete hollow block masonry walls without vertical load have a little crack at failure,but the main crack is obvious.The wal... |
