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。
In order to study the effect of the two parameters of the ratio of height to thickness and the ratio of reinforcement on the compressive performance of recycled concrete block filled wick wall, the axial compression tests of nine walls were carried out. The test results show that: the reinforcement can significantly improve the compressive capacity of the axial compressive strength of the wall, but the out-of-plane displacement of the un-reinforced concrete wall is smaller than that of the reinforced concrete wall; Ductility is better. Based on the test data and GB 50003-2011 “Code for Design of Masonry Structures”, the theoretical formula of compressive bearing capacity of assembled recycled concrete block filled wick wall is given.
