| 摘 要： | 对两个1/6缩尺的开洞核心筒结构模型进行了偏心水平荷载作用下的低周反复荷载试验研究,其中包括一个普通开洞混凝土核心筒和一个内藏钢桁架开洞混凝土组合核心筒。在试验的基础上,对比分析了两个试件的承载力、刚度、延性、滞回特性、耗能能力、破坏特征以及抗震机理。试验研究表明,在偏心水平荷载作用下,内藏钢桁架开洞混凝土组合核心筒比普通开洞混凝土核心筒抗震能力显著提高。

| Abstract: | Two core walls on the scale of 1/6 including a normal reinforced concrete perforated core wall and a reinforced concrete composite perforated core wall with concealed steel truss were designed.The experimental study on the seismic behavior of two core walls subjected to eccentric horizontal loading was carried out.Load-carrying capacity,stiffness,ductility,hysteretic behavior,energy dissipation and failure mechanism of the core walls were discussed.The test results show that the seismic performance of the core walls is improved greatly by the concealed steel truss. |

| Keywords: | reinforced concrete steel truss core wall eccentric loading seismic performance |
