摘　　要：对4个不同轴压比、配钢率、加载方向的实腹式型钢混凝土(SSRC)十字形异形柱进行低周反复荷载试验,得到其荷载-位移滞回曲线、位移延性、强度衰减及耗能能力等抗震性能。与空腹式型钢混凝土(LSRC)十字形异形柱的抗震性能进行对比,分析结果表明:实腹式型钢混凝土十字形异形柱滞回曲线饱满,强度衰减幅度较小,耗能能力较高,延性良好。Seismic behaviors of solid-web steel reinforced concrete （SSRC） cross-shaped columns were investigated through low cycle reversed loading testing of four column specimens with various axial compression ratios, steel ratios and loading directions. Column failure processes and patterns were recorded. The load- displacement hysteretic curve, ductility, strength deterioration, and energy dissipating capacity were analyzed. Comparison between the SSRC cross-shaped column and the lattice style steel reinforced concrete （LSRC） cross-shaped column showed that the solid-web specimens had more energy dissipation capacities. The strength deterioration of SSRC specimens was not so significant. The SSRC specimens also have good ductility.
