摘　　要：钢结构自重轻,材料力学性能远高于砖木、混凝土等其它传统建筑材料,能适应各种结构形式,赋予建筑师更大的自由创意空间。某钢结构大天蓬为3斜柱支撑的飘逸建筑造型,在钢构设计中首次应用钢箱梁与斜钢管柱刚性连接,并带施工临时支托肋板的新型节点、钢箱梁与钢筋混凝土结构主体部分的T形半刚性接节点实际案例,相关节点设计应可借鉴用于其它类似钢构工程。Steel structure has light self weight and far higher mechanical properties than other traditional building materials such as brick,wood and concrete.It can adapt to various structural forms and give architects more free and creative space.In a case,the steel structure canopy is a floating building shape supported by 3 inclined columns.For the first time,a new type of joint with steel box girder and inclined steel tube column rigidly joints with temporary supporting rib plate is applied in te steel structure design,and a practical case of Tshaped semi-rigid joint between steel box girder and main part of reinforced concrete structure is presented.The relevant joint design should be used for reference in other similar steel structure projects.
