［摘要］为了研究高配箍率钢筋混凝土柱在高轴压比下的受力性能，对两组轴压比分别为0.4和0.6、体积配箍率为1.89%的4个试件进行单调加载和低周反复加载试验，研究了钢筋混凝土柱的破坏形态、承载能力、滞回特性和耗能能力。结果表明：试件变形主要以弯曲变形为主，弯曲变形约占总变形的90%，当配箍率为1.89%时，即使轴压比较大，试件仍具有较强承载能力、变形能力和耗能能力。

Abstract: In order to study the mechanical performance of reinforced concrete column with high stirrup ratio under high axial compression ratio, low cyclic loading test and monotonic loading test were conducted on four reinforced concrete columns under axial compression ratio of 0.4 and 0.6 and stirrup ratio of 1.89%. The failure mode, bearing capacity, hysteretic characteristics and energy dissipation capacity were studied. The results show that bending deformation accounts for about 90% of the total deformation, and the members have strong bearing capacity, deformation ability and energy dissipation capacity when stirrup ratio is 1.89% despite the high axial compression ratio.

Keywords: reinforced concrete column; high axial compression ratio; high stirrup ratio; mechanical performance
