摘要(Abstract):

通过对5个1:8缩尺比例的钢骨高强混凝土(>C75)柱的伪静力试验,研究了在不同轴压力和配箍率条件下的破坏形态、承载力、延性与耗能能力,并经理论分析提出了钢骨高强混凝土柱的怕压比与轴力比限值。
The tests of five steel reinforced high strength concrete (> C75) columns (reduced scale is 1: 8) under the cyclic reversed loading have been carried out, which vary in the magnitude of axial force and band content. The aseismatic behaviors are compared with emphasis on failure pattern, beaing capacity, ductility and energy dissipation capacity. Limited values of axial compression ratio and axial force ratio of this kind of column are proposed in terms of experimental results and theoretical analysis.
