【摘要】 对两个1/6缩尺的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,其中包括一个普通混凝土核心筒和一个内藏钢桁架混凝土组合核心筒。在试验的基础上,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:偏心水平荷载作用下,内藏钢桁架混凝土组合核心筒比普通混凝土核心筒抗震能力显著提高。更多还原

【Abstract】 In this paper, two 1/6 scale core walls including a normal reinforced concrete core wall and a reinforced concrete composite 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. The load-carrying capacity, stiffness, ductility, hysteretic behavior , energy dissipation and failure mechanism of the core walls are discussed. The tested results are shown that the seismic performance of the core wall is improved greatly with the concealed steel truss.更多还原
