厦门高崎国际机场T4航站楼屋盖采用双向平面桁架结构体系,屋面采用双曲面造型的金属屋面系统。以该航站楼工程为背景,分析了屋盖结构体系和金属屋面设计及钢结构计算要点。由于结构的跨度大,风荷载分布形式复杂,为确保结构的安全、合理,针对结构设计中的关键问题,采用模拟建筑物实际体型风洞试验和数值模拟风洞技术,得到屋面荷载的分布和大小,保证风荷载取值的正确性。进而对屋面系统的抗风承载力进行分析和设计优化。研究结果表明该航站楼采用的屋盖结构体系是合理有效的,可为类似工程设计提供参考。
Xiamen Takasaki International Airport Terminal T4 T4 roof using two-way plane truss structure system, the use of hyperbolic roofing of the metal roofing system. Taking the terminal project as a background, the key points of roof structure system, metal roof design and steel structure calculation are analyzed. Due to the large span of the structure and complicated wind load distribution, in order to ensure the structural safety and reasonableness, the actual body shape wind tunnel test and the numerical simulation wind tunnel test are adopted to simulate the key problems in the structural design. Size, to ensure the correctness of wind load value. Then the wind-resistant capacity of roofing system is analyzed and designed and optimized. The research results show that the roof structure system used in this terminal is reasonable and effective, which can provide reference for similar engineering design.
