通过 6根配置LL5 5 0冷轧带肋箍筋的高强混凝土柱的抗震性能试验 ,研究了LL5 5 0冷轧带肋箍筋高强混凝土柱在不同轴压比和水平往复荷载作用下的破坏规律 ,以及轴压比、箍筋间距和纵向钢筋配筋率等对压弯构件延性的影响。综合已有高强混凝土压弯构件的试验资料 ,给出了配LL5 5 0冷轧带肋箍筋高强混凝土柱抗震设计中最小含箍特征值限值的建议。 Through the experiment of six high strength concrete columns with LL550 cold-rolled ribbed stirrup, the failure of LL550 cold-rolled ribbed stirrup high-strength concrete columns under different axial compression ratio and horizontal reciprocating load was studied Law, as well as the influence of axial compression ratio, stirrup spacing and longitudinal reinforcement ratio on the ductility of the RC members. Based on the experimental data of the existing high-strength concrete compression-bending members, some suggestions on the minimum hoop characteristic value in the seismic design of LL550 cold-rolled ribbed high-strength concrete columns are given.
