摘要
为研究再生粗骨料对方钢管约束再生混凝土柱受力性能的影响,制作9根试件并进行轴压静载试验。试验结果表明:轴压条件下,试件主要发生斜压破坏,峰值荷载随再生粗骨料取代率的增加而略有降低。基于试验实测数据和统一强度理论,提出构件轴压承载力计算公式,可为工程设计人员提供一定的参考。
By the axial compression tests on a total of 9 Recycled Aggregate Concrete(RAC)columns confined by square steel tube,the effect of recycled coarse aggregate replacement percentage on the axial compressive strength was studied.Test results indicated that the failure mode of square steel tube was diagonal shear failure.With the increase of the replacement rate of recycled coarse aggregate,the peak load of the recycled aggregate concrete filled square steel tube column decreased slightly.The simplified calculation method of bearing capacity was discussed based on test data and unified strength theory,which can provide a reference for engineering designers.
