建筑钢结构连接节点的设计与施工技术分析

Analysis of Design and Construction Technology of Building Steel Structure Connection Joints

随着高层建筑的兴起,钢结构因其高强、轻质、施工便捷、抗震优良的特点得到了广泛应用,而连接节点作为钢结构体系的核心部位,直接影响结构的安全性和经济性,从设计原则和施工技术两个方面,分析了高层建筑钢结构连接节点的安全性、可靠性和经济性原则,并探讨了焊接、螺栓连接、吊装等施工技术。结合上海中心大厦、北京国家体育场(鸟巢)和深圳平安金融中心的实际案例,深入展示了连接节点的设计与施工技术在实践中的应用。

With the emergency of high-rise buildings,steel structures have been widely used because of the high strength,light weight,convenient construction and excellent seismic resistance.As the core parts of the steel structure system,the connecting joints directly affect the safety and economy of the structure.In the aspects of design principles and construction technology,the safety,reliability and economic principles of high-rise building steel structure connection joints are analyzed,and the construction technologies such as welding,bolting connection and hoisting are discussed.Combined with the actual cases of Shanghai Tower,Beijing National Stadium(Bird's Nest)and Shenzhen Ping An Finance Center,the application of the design and construction technology of connecting nodes in practice is exhibited.
