摘要:杭州萧山国际机场T4航站楼单体众多且高度不一,为考虑风荷载下各单体之间的相互干扰效应,设计了风洞试验,试验结果表明尾流区涡流激振直接影响相互干扰增大系数。为准确分析大跨度结构、大悬挑结构的边柱受力,对竖向地震作用进行了计算分析,结果表明在确定柱轴压比时不可忽视竖向地震力。为避免地震波选择时的随机性,通过施加强制位移的分析方法,对单体下部设缝而屋面连为整体的结构受力性能进行研究,证明可包络最不利的地震波状况。为增加建筑净高,通过对幕墙柱和屋面钢梁的联合受力分析,证明可将屋面单跨结构变为多跨结构,使梁构件跨高比达50以上。为保证多层大跨登机桥的舒适度,通过人行荷载激励测试证明了设计参数选择的正确性。

Abstract: The T4 terminal of Hangzhou Xiaoshan International Airport has many single buildings with different heights,in order to consider the mutual interference effect between each building under wind load,the wind tunnel test was designed,the test results show that the eddy current excitation in the wake area directly effects the mutual interference increase coefficient.In order to accurately analyze the forces acting on the side columns of large-span structure and large cantilevered structure,vertical seismic action was calculated and analyzed,the results shows that the vertical seismic force can not be ignored when determining the axial compression ratio of columns.For avoiding the randomness of seismic wave selection,by applying the analysis method of forced displacement,stress performance of the structure with joints in the lower part of a single building and the roof connected as a whole was studied,and it is proved that the most unfavorable seismic wave conditions can be enveloped.For increasing the clear height of the building,through the joint stress analysis of curtain wall columns and roof steel beams,it is proved that the roof single span structure can be changed into a multi span structure,and the span height ratio of the beam members can reach more than 50.In order to ensure the comfort of the multi-storey and large-span boarding bridge,the correctness of the design parameters was proved by the pedestrian load excitation test.
Keywords: Hangzhou Xiaoshan International Airport; large-span structure; large cantilevered structure; mutual interference increase coefficient; comfort; pedestrian load excitation
