【摘要】 钢筋混凝土剪力墙和筒体结构是高层建筑中最广泛应用的结构体系。随着人们对建筑功能及美学的不断追求,现代高层建筑变得越来越不规则,带型钢混凝土转换层的结构已逐渐成为设计人员选择的结构布置方式之一。为了确保结构的安全性,型钢混凝土转换梁与剪力墙之间的可靠连接更显重要。但是国内外型钢混凝土转换梁与剪力墙连接节点的试验研究进行的很少。本文在广泛阅读国内外相关文献,分析整理已完成的型钢混凝土转换梁一剪力墙节点试件在低周反复荷载作用下的模型试验的基础上,进一步利用有限元法,合理选择模型和材料本构关系,设置有关参数,对节点进行反复荷载作用下的非线性有限元分析,研究了该节点结构内部各部件应力分布、传力机理、破坏形态及滞回特性等性能,为该结构形式的工程应用提供有益的理论依据。更多还原

【Abstract】 Reinforced concrete shear-wall and tube building are the most popular structure systems for high-rise buildings. With pursuit of multi-purpose and aesthetics of architecture, modern high-rise buildings becomes more and more irregular, so many structure designers prefer to choose the reinforced concrete transfer beam systems. The connections of the reinforced concrete transfer beam and shear-wall must be reliable to guarantee the safety of the whole buildings. But there are fewer experiments and research of the reinforced concrete transfer beam and shear-wall in domestic and international research works. The main work of this thesis is to use finite element method to study the behaviour of the joints of reinforced concrete transfer beam and shear-wall under reversed loading by choosing models and setting relevant parameters reasonably. The results are then compared with testing results. The mechanism of force transfer, failure state and seismic performance are investigated in order to provide instructions for application of the connection in the future.更多还原
