摘　　要：钢管结构以其一系列独特的优越性能,不仅在海洋工程、桥梁工程、塔桅工程、起重机械工程中得到了大范围的应用,而且在工业及民用建筑工程中的应用也日益广泛.但在实际工程的设计过程中,设计人员往往只重视验算构件而忽视对节点强度的计算.本文针对某钢结构办公楼工程,根据现行设计规范对其桁架节点进行了全面的复核计算.对强度不满足要求的节点进行了加固设计,并通过有限元软件对节点的加固后强度进行了计算分析.最后总结了钢管结构初期设计以及加固设计过程中需要注意的问题并给出了相关建议.Tubular structure is increasingly applied not only in ocean engineering, bridge construction, but also in civil engineering because of its unique superior performance. At the design procedure of tubular structure, the designers often pay attention to safety analysis of structural members, but ignore the loading capacity of tubular joints. In this paper, we check all the steel truss joints of a office building according to the applicable codes. Reinforcement design and analysis of the joints which are not satisfied according to ,the design codes is presented. At the end of this paper, common problems and relative suggestions for design procedure and reinforcement design are summarized.
