[摘要]大型机场航站楼因建筑功能特别重要,一般要求在遭遇地震作用时仍能保持正常运转。从地震损伤控制的角度,研究了青岛胶东国际机场航站楼结构的消能减震方案。对比分析表明,设置黏滞阻尼器为航站楼框架结构增加了抗震防线,结构耗能能力明显增强,主体框架损伤程度大幅度降低,有效地提高了结构遭遇较大地震作用时保持正常运转的可靠度。

Abstract:Terminal building of main airport, owing to its particularly important architectural function, is usually requested to remain functional after hit by earthquakes. The design scheme of energy dissipation and seismic mitigation for the terminal building of Qingdao Jiaodong International Airport was investigated from the viewpoint of earthquake-induced damage control. Comparison of analysis results indicates that additional defense line is equipped to the original bare frame structure, thus the energy dissipation capacity is increased evidently. The earthquake-induced damage of main frame is reduced substantially, and the structural reliability of remaining functional under future major earthquakes is effectively enhanced.
Keywords:Qingdao Jiaodong International Airport; terminal building; frame structure; seismic mitigation; damage control
