摘要
厦门翔安国际机场航站楼属于超长大跨度结构,其结构的温度作用取值方法及温度效应对结构受力的影响比较复杂.确定超长大跨度结构正、负温差时,对于混凝土结构需要考虑混凝土收缩当量温降的影响,对于钢结构需要考虑太阳辐射引起的钢结构温升的影响.在使用阶段根据混凝土结构和钢结构的受力与变形特点,分析了超长航站楼结构温度效应分布规律,并通过使用阶段与施工阶段温度效应对比分析,得出了超长航站楼结构设计应由施工阶段控制的结论.给出的超长结构温度作用取值方法以及温度效应分布规律等,对后续超长结构设计具有很好的指导作用.
Xiamen Xiang'an International Airport terminal is of super length and large span structure,with the method of temperature action value and the influence of temperature effect on structural stress both being complex.Furthermore,when determining the positive and negative temperature variations of the super length and large span structure,for concrete structure we should consider the effect of concrete shrinkage temperature drop,and for steel structure we need to consider the influence of steel structure temperature rise caused by solar radiation.Based on the stress and deformation characteristics of concrete structure and steel structure in application stage,we analyze the distribution law of temperature effect of super long terminal building.Through comparing and analyzing the temperature effect between application stage and construction stage,we conclude that the structural design of the super long terminal should be controlled in the construction stage.The proposed method of temperature action value and the distribution law of temperature effect can provide guidance for the design of super long structure.
