摘　　要：厦门国际会展中心三期大跨度屋盖结构采用99m和72m跨度张弦桁架。为抵抗巨大风吸力,屋盖采用混凝土板配重。局部存在27m跨楼盖,采用双向桁架组合楼盖,为减小楼盖振动,设计中采用了TMD减振设备。对于大跨度屋盖,介绍了新型屋盖体系、屋面风洞试验结果以及设计风荷载取值、温度作用计算参数选取方法、张弦桁架及混凝土屋盖的计算结果、混凝土屋盖施工控制等关键设计内容。对于大跨楼盖,介绍了楼盖体系、楼盖振动计算及TMD减振专项设计内容。Chord-tension trusses with 99m and 72m span were adopted for large span roof of Xiamen International Conference and Exhibition Center phase Ⅲ.Concrete counterweight was used to prevent the great wind uplift.Two-way truss and combination floor system with TMD systems were used to reduce the floor vibration for the local 27m span across floor.The new roof system,roof wind tunnel test results and wind load for design,parameter selection method of temperature effect analysis,the calculation results of chord-tension truss and the concrete roof,the construction control rules,and other key design contents were introduced for large span roof.The combination floor system,floor vibration calculation and TMD vibration reduction were introduced for large span floor.
