摘　　要：完成了6根不同再生骨料取代率下的轴心、偏心柱受压试验,研究了再生混凝土柱的破坏形态和承载力等受压性能,并与普通混凝土柱进行对比分析,基于试验结果的分析,探讨了现行规范受压承载力的计算方法对于再生混凝土柱的适用性。The axial and eccentric compression performances of recycled concrete columns with different replacement percentage of recycled coarse aggregate were experimentally investigated.The loading capacity and the failure modes of the recycled concrete columns were mainly discussed.Based on the results of the experiment, it is proved that it is feasible to apply the design standard for the normal aggregate concrete columns to the loading capacity calculation of recycled aggregate concrete columns.
