【摘要】 基于以往的研究成果提出了一种改进型节点———焊接孔扩大型狗骨节点,利用通用有限元程序Ansys5.7对其进行了受力分析和抗震性能分析.结果表明,焊接孔扩大型狗骨节点兼有焊接孔扩大型节点和普通狗骨节点的优点,其塑性变形远远大于两者,应力集中程度得到明显改善,是一种值得进一步研究的节点形式.更多还原

【Abstract】 The authors proposed a new steel frame connection called modified Dog_bone connection with oval weld holes in this work. With finite elements analysis procedure, the authors analyze the connection on mechanics and anti_seismic performance. The results indicate the modified connection has the merits of both general Dog_bone connections and connections with oval weld holes. Its plastic deformation is larger and its stresss concentraion is less than another two. It is a connection that is worth studying in detail.更多还原
