摘要:
提出了内藏钢桁架带洞口混凝土组合核心筒,该组合核心筒包含2种组合,即不同受力体系-桁架与核心筒的组合、不同材料-型钢与混凝土的组合,形成了双重组合核心筒.对2个1/6缩尺的带洞口核心筒结构模型进行了低周反复荷载下的抗震性能试验研究,其中包括一个普通带洞口混凝土核心筒和一个内藏钢桁架带洞口混凝土组合核心筒.在试验的基础上,对比分析了2个试件的刚度及其衰减过程、承载力、延性、滞回特性、耗能及破坏特征.试验及分析表明,内藏钢桁架带洞口混凝土组合核心筒比普通带洞口混凝土核心筒抗震能力明显提高.建立了内藏钢桁架带洞口混凝土组合核心筒的承载力计算模型,计算结果与实测值符合较好.提出了该新型组合核心筒抗震设计的建议.
Abstract:
Reinforced concrete composite perforated core wall with concealed steel truss has been proposed. This new composite core wall includes two kinds of composition. One is composition of two bearing systems, including truss and core wall, the other is composition of two materials, including steel and concrete. Two 1/6 scale perforated core walls specimens were designed,including a normal reinforced concrete perforated core wall and a reinforced concrete composite perforated core wall with concealed steel truss. The experimental research on their seismic performance under cyclic loading was carried out. Their load-carrying capacity, stiffness, ductility, hysteretic behavior, energy dissipation and failure phenomena of the core walls are discussed. The test results show that the seismic performance of core wall is improved greatly by the concealed steel truss. The mechanical models for calculating load-carrying capacity of the core wall are proposed, and the theoretical results agree well with those from experiments. Some suggestions for seismic design of this new composite perforated core wall are proposed.
