高强混凝土短柱抗震性能试验研究

Test research of high-strength concrete short columns in antiseismic performance

通过对高强混凝土短柱在轴压力和水平反复荷载作用下抗震性能的试验研究 ,分析了轴压比和配箍率对高强混凝土短柱延性的影响 ,得出了满足一定位移延性 (μΔ≥ 3 )要求的高强混凝土短柱的轴压比限值和柱箍筋加密区最小体积配箍率的建议值 。

The test research of the high\|strength concrete short columns in antiseismic performance is carried out. The suggested values of the axial pressure ratio and hooped reinforcement ratio are obtained through the test, which satisfy the certain requirements of ductility.
