为了研究城市垃圾熔渣粗、细骨料在建筑结构上循环利用的可能性,本文着眼于力学性能方面,对城市垃圾熔渣钢筋混凝土柱以及对比用普通钢筋混凝土柱做了水平低周反复加载试验,研究了城市垃圾熔渣钢筋混凝土柱的破坏形式、承载能力、滞回特性以及耗能等性能。试验结果表明,在柱轴压比相同,混凝土强度较接近的情况下,城市垃圾熔渣钢筋混凝土柱在破坏形式、承载能力以及耗能能力等方面与普通钢筋混凝土柱相比并没有明显降低,表现出良好的变形能力以及吸能能力;在抗震性能方面,单从结构力学角度来看,城市垃圾熔渣混凝土应用在建筑结构是上完全可行的。
In order to study the possibility of coarse and fine aggregates of municipal solid waste recycling on the building structure, this paper focuses on the mechanical properties of the city rubbish slag reinforced concrete columns and compared with ordinary reinforced concrete columns made horizontal low cycle repeated loading Experiments were carried out to study the failure modes, bearing capacity, hysteresis characteristics and energy dissipation of the city garbage slag concrete column. The test results show that compared with ordinary reinforced concrete columns, the urban rubbish-filled RC columns have no obvious reduction in the form of failure, bearing capacity and energy dissipation compared with the same column axial compression ratio and concrete strength. Showing good deformation capacity and energy absorption capacity; in the seismic performance, from a structural mechanics point of view, the application of urban waste slag concrete construction is feasible.
