| 摘 要： | 进行了12个钢管再生混凝土和12个配置螺旋箍筋的钢筋再生混凝土轴压短柱试验，在用钢量相同的情况下，对比分析了钢管再生混凝土短柱与钢筋再生混凝土短柱二者轴压力学性能的差异；分析了核心再生混凝土强度及再生粗骨料取代率等主要试验参数对钢管再生混凝土与钢筋再生混凝土轴压短柱力学性能的影响。试验结果表明：与用钢量相同的钢筋再生混凝土试件相比，钢管再生混凝土试件表现出较好的力学性能；钢管再生混凝土轴压短柱套箍系数较小时（ξ<1.0），发生剪切破坏；再生粗骨料取代率对钢管混凝土短柱极限荷载的影响幅度相对钢筋再生混凝土短柱较小；核心再生混凝土强度对轴压短柱力学性能的影响规律与相应的钢管普通混凝土短柱和钢筋普通混凝土短柱类似。

| Abstract: | This paper presented experimental study on 12 recycled aggregate concrete filled steel tubular(RACFST) stubs and 12 reinforced recycled aggregate concrete(RRAC) stubs with spiral reinforcement under axial compressive loading.To highlight the beneficial effects of the confinement effects on the mechanical behavior of RACFST specimens,the weight of the steel used in RACFST specimens and their companion RRAC specimens are the same.Influences of the parameters including concrete strength and recycled coarse agg... |
