进行了4个不同轴压比、含钢率、加载方向的型钢高性能混凝土十字形异形柱的低周反复加载试验，得到试件各阶段开裂变形及破坏形态，分析试件破坏机理，得出其荷载?位移滞回曲线、骨架曲线、刚度退化、强度衰减、耗能能力。通过试验实施及相关理论计算得到相关结论，SSRHC十字形异形柱试件在剪跨比为3?25时发生弯曲破坏形态，轴压比、含钢率、不同加载方向对试件抗震性能有不同影响。

A series of low cyclic loading tests were carried out on 4 solid?web SSRHC beams with different axial compression ratio, steel ratio and loading direction. Through the observation of cracking and failure modes, the load?displacement hysteresis curves, skeleton curves, stiffness degradation, strength degradation and energy dissipation capacity were obtained. The test result indicates that the SSRHC cross?shaped column will bend failure with a shear span ratio of 3?25. Axial compression ratio, steel ratio and loading direction have different influence on seismic behavior of specimens.
