城市垃圾熔渣混凝土柱抗震性能的试验研究

Experimental Research on the Seismic Behavior of Columns with City Garbage Melting Slag Concrete

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。

For researching the recycled using possibility in building structure with coarse and fine aggregate used city garbage melting slag, the ehief aim to the field of mechanic property, carry horizontal low repetition load experiment for reinforced concrete column between city garbage melting slag and reinforced concrete compared, and research the destructive form, bearing capability, history characteristic, and energy absorption capability is focused in this paper. The experiment shows, under the same axis-pressure ratio and the proximity strength, comparing the ordinary reinforced concrete column, the concrete column with city garbage melting slag, whose destructive form, bearing capability and seismic behavior do not declined apparently, which empress good energy absorption capability in seismic aspect. Only from the inspect of mechanic structure, the application of city garbage melting slag concrete in building structure is completely possible.
