【摘要】 目的为了得到合理的节点形式,研究在静载下屈曲约束支撑与混凝土梁的连接节点性能.方法设计屈曲约束支撑与混凝土梁的两种连接节点,分别是栓钉连接式节点和型钢连接式节点,借助大型有限元分析软件ABAQUS对这两种节点在静载下的性能进行分析.结果两种形式节点的破坏原因都是由于节点板挤压部分的混凝土被压碎造成节点刚度变化,承载力急剧下降,节点破坏.两种形式节点的延性基本相同,均满足设计要求,但是型钢连接式的节点承载力约为栓钉连接式节点的1.16倍.结论两种形式节点受力均匀,传力明确,具有良好的性能,能够满足承载力的需要和延性的要求.更多还原

【Abstract】 The purpose of this paper is to get rational joints,and do research the performance of joints between BRB and concrete beams under monotonic loading.The joint between BRB and concrete beam is designed in two forms,namely,stud-connected joint and steel-connected joint.Then finite element analysis of two joints under monotonic loading is made using software ABAQUS.The study shows that the decrease of the bearing capability and the destruction of joints under monotonic loading are due to the failure of the concrete in contact with the edge of the gusset plate.The displacement ductility of the two types of joints is basically the same and it is good enough to meet the requirements.But the bearing capability of the steel-connected joint is 1.16 times as the bearing capability of the stud-connected joint.Two joints force evenly,power transmission clear,and have good performance.Meanwhile,the displacement ductility and bearing capability of the two types of joints is good enough to meet the requirements.更多还原
