【摘要】 提出一种内部型钢由花纹钢板制作的花纹型钢混凝土组合柱。通过设计2个花纹高度不同的新型试件和1个普通型钢混凝土试件的低周反复荷载试验，研究试件的破坏形态、滞回骨架特性、刚度退化、内置型钢的应变变化规律等，分析型钢表面的花纹高度对型钢混凝土组合结构抗震性能的影响。试验结果表明，相较于普通型钢混凝土柱，花纹型钢混凝土柱的承载能力、延性、变形和耗能能力等抗震性能均得到有效提高，且型钢表面的花纹凸起高度越大，提高效果越好。更多还原

【Abstract】 In this paper,a kind of steel reinforced concrete(SRC)composite column with built-in steel made of checkered steel plate is proposed. Two specimens with different pattern heights and one common steel reinforced concrete specimen were designed.The failure mode,hysteresis skeleton characteristics and stiffness degradation of the column,as well as the strain variation law of the built-in steel were studied by conducting low cycle cyclic loading tests. The influence of pattern height on the seismic performance of the SRC columns was analyzed. The test results show that the bearing capacity,ductility,deformation and energy dissipation capacity of the SRC columns are effectively improved as compared with the ordinary column,and the greater the patterned convex height on the steel surface,the better the column effect.更多还原
