摘　　要： 本文通过对1∶2比例模型的普通混凝土框架和两榀再生骨料掺量为50%的再生混凝土框架(其中一榀再生混凝土框架用再生轻质砌块作填充墙),在恒定的竖向轴压荷载和水平低周反复荷载作用下进行了抗震性能的对比试验,研究了再生混凝土框架和再生砌块填充墙再生混凝土框架在低周反复荷载作用下的破坏机制、承载力、滞回特性、延性、强度退化、刚度退化和耗能等问题,并和普通混凝土框架进行对比分析,为再生轻质砌块和再生混凝土结构的深入分析研究和实际应用提供了理论基础。 Seismic behaviors of one ordinary concrete frame and two recycled concrete frames whose scales are 1 ： 2 entirely are studied and compared under low reversed cyclic lateral loading in this paper. One of the recycled concrete frames in which the recycled aggregate replacement ratios are 50 percent is filled with lightweight recycled masonry blocks. Emphasis was put on the evaluation of the failure mechanism, hysteresis loops, displacement ductility, deterioration of strength and stiffness and energy dissipation of recycled concrete frames under seismic loads, This work provides theoretical base for the further study and practical application of lightweight recycled masonry blocks and recycled concrete structure.
