摘  要:为了研究高厚比和配筋率两个参数对装配式再生混凝土砌块灌芯墙体抗压性能的影响,进行了9片墙体的轴压试验。试验结果表明:配筋能够明显提高此墙体轴心抗压承载力,但未配筋墙体的平面外位移较配筋墙体的小;高厚比越大,配筋的灌芯墙体延性越好。基于试验数据和GB 50003—2011《砌体结构设计规范》给出了装配式再生混凝土砌块灌芯墙体抗压承载力的理论计算式。To study the effect of depth-thickness ratio and reinforcement ratio on the compression performance of prefabricated recycled concrete block grouted-wall,axial compression tests on nine walls were carried out. The test results showed that reinforcement could improve the wall 's axial compressive bearing capacity,but out-of-plane displacement of non-reinforced wall was smaller than that of reinforced wall; the greater the depth-thickness ratio,the better ductility of the reinforced grouted-wall was. Based on experimental data and the code for design of masonry structure,theoretical formula for compressive bearing capacity of prefabricated recycled concrete block grouted-wall was given.
