摘要
对17个型钢混凝土(SRC)异形柱试件采用“建研式”加载装置进行低周反复荷载试验,观察了不同配钢形式的SRC异形柱的受力过程和破坏形态;分析了SRC异形柱的破坏特点,荷载-位移滞回曲线及骨架曲线、承载力、位移延性、刚度退化和耗能能力等力学性能。试验研究结果表明:SRC异形柱的主要破坏形态是剪切斜压破坏和弯曲型破坏,破坏主要发生在与加载方向平行的柱肢,滞回曲线对称、饱满,试件延性好,极限侧移角大,具有良好的抗震能力,因此,可以推广应用于高抗震设防烈度区的建筑以及高层建筑中。
According to the experimental studies on 17 specimens of steel reinforced concrete(SRC) special-shaped columns under low cyclic reversed loading,the failure process and patterns were obtained.The failure characteristics,mechanical behaviors of SRC special-shaped columns such as the loading-displacement hysteretic loops and skeleton curves,load bearing capacity,displacement ductility,rigidity degradation and energy dissipation are analyzed.The experimental study indicates that the major failures of SRC special-shaped columns are shear diagonal compression failure and flexural failure,and the destruction mainly occurs in the part of the cross section which parallels the force direction.The hysteretic loops of SRC special-shaped columns are symmetric and plump.The specimens had good ductility and large rotation capacity,indicating excellent seismic behavior.Such columns can be adopted in high-rise buildings and the construction in high seismic fortification zone.
