摘　　要：对4片再生混凝土自保温空心砌块进行了不同竖向荷载条件下的水平低周荷载试验研究,分析新型砌块的承载能力、破坏形态、耗能性能。试验研究表明,新型混凝土保温空心砌体具有一定的承重能力,可用于村镇多层民房建筑的保温承重墙。但不同轴压比及竖向荷载加载方式对墙片的破坏形态和耗能能力有较大影响,在无配筋的情况下延性较差,建议在实际工程应用中,应参考砌体结构规范进行配筋设计,以提高其抗震性能。Experimental investigations of new type recycled aggregate insulation hollow block, effect of loading mode and axial compression ratio on the failure mode and energy dissipation capacity of the masonry were analyzed though low cyclic reversed loading test. Experimental results show that the new type insulation hollow masonry has enough vertical bearing capacity, which can be used in low cost building. Meanwhile the deformation and ductility of the masonry is poor. In engineering applications, special attentions should be paid to reinforced construction, and bonding strength should he guaranteed.
