Axial Bearing Capacity Analysis of H-Section Steel-Reinforced Recycled Aggregate Concrete Filled Circular Steel Tube Stub Columns

  • 摘要: 为了研究圆钢管H型钢再生混凝土短柱轴压力学性能,对此类构件轴压承载力计算公式进行了理论推导,基于极限分析法,运用双剪统一强度理论,并依据H型钢和钢管对核心区再生混凝土约束效果的不同,分别计算H型钢约束区再生混凝土和钢管约束区再生混凝土承载力,提出一套圆钢管H型钢再生混凝土短柱轴压承载力计算公式,考虑了钢管内径厚比、套箍系数、H型钢配钢指标以及再生粗骨料取代率对短柱轴压承载力的影响, 同时也适用于无H型钢的圆钢管再生混凝土短柱轴压承载力计算. 将推导得到的钢管有效约束力代入承载力计算公式所得结果与相关试验结果对比误差在10%以内,吻合较好,验证了承载力计算公式的有效性和精确度.
