摘　　要：通过5根双钢管高强混凝土柱承受轴力和低周反复水平荷载作用试验,研究了双钢管高强混凝土柱的抗震性能,讨论了该柱压弯承载力计算公式的适用性.结果表明:双钢管高强混凝土柱具有较高的压弯承载力及优良的抗震性能.Tests of five double high strength concrete filled steel tube(CFST) columns under constant axial compression and low-period alternating horizontal loads are carried out to study the seismic behaviors of double high strength CFST columns and usability of formulation of compression-bending capacity.The tests prove that double high strength CFST columns can provide higher compression-bending capacity and advanced seismic behaviors.

关 键 词：双钢管高强混凝土柱 抗震性能 延性 压弯承载力
