摘要

昆明新国际机场航站楼是目前世界上最大的隔震建筑之一。对隔震层的布置方案进行了详细地阐述,建立了航站楼的有限元模型并进行动力反应分析。对昆明新国际机场航站楼进行了振动台试验研究,试验中模型结构的缩比为1/60,隔震层也进行了相应的简化布置。试验结果表明,隔震结构的减振效果能达到50%。最后对原型结构进行了抗震性能分析,探讨了原型结构在不同水准地震作用下的动力特性、加速度和位移反应,并与试验结果相对比,有限元分析结果与试验结果吻合较好。理论与试验证明,昆明新国际机场航站楼隔震机理清晰且隔震效果良好,大跨结构应用基础隔震技术是有效的。

Abstract

The Kunming new international airport terminal is one of the world’s largest seismic isolation buildings at present. The layout scheme of the seismic isolation layer is described in detail. The finite element model of the terminal is established and the dynamic responses are also analyzed. The shaking table test is carried out for the Kunming new international airport terminal. The scale factor of the model structure used in the test is 1/60. And the layout of the seismic isolation layer is also simplified. The results show the vibration-reduction effects of the seismic isolation building are about 50%. Finally, the seismic performances of the prototype structure are analyzed. Dynamic characteristics, acceleration responses and displacement responses of the prototype structure are investigated under different levels of earthquake. Compared with the shaking table test’s results, it is shown that the finite element analysis results are agreed well with the experimental results. The Kunming new international airport has clear isolation mechanism and good isolation effect with the theoretical and experimental proof. It is feasible and effective for applying the base isolation technology to long-span structures.
