【摘要】 提出了钢管混凝土叠合柱边框内藏钢板-钢撑混凝土组合核心筒,为了解该新型多重组合核心筒的抗震性能和破坏机理,文中进行了1个1/6缩尺的钢管混凝土叠合柱边框内藏钢板-钢撑带洞口混凝土组合核心筒的低周反复荷载试验研究。在试验研究基础上,分析了该多重组合核心筒的承载力、滞回特性、延性、刚度衰减和破坏形态。研究结果表明:钢管混凝土叠合柱边框内藏钢板-钢撑带洞口混凝土组合核心筒的抗震性能良好。更多还原

【Abstract】 A new type of RC core wall with steel tube-reinforced concrete columns and concealed steel plate is proposed.In order to know the seismic behavior of the composite core walls,a cyclic loading test on the 1/6 scale RC core walls with holes was carried out in this paper.Based on the experiment,the load-carrying capacity,hysteretic behavior,ductility,stiffness attenuation and failure are discussed.The tested results show that the seismic performance of the RC core walls with steel tube-reinforced concrete columns and concealed steel plate is better.更多还原
