Abstract: The T4 terminal of Hangzhou Xiaoshan International Airport has many single buildings with different heights,inorder 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 increasecoefficient. In order to accurately analyze the forces acting on the side columns of large-span structure and largecantilevered structure, vertical seismic action was calculated and analyzed,the results shows that the vertical seismic forcecan not be ignored when determining the axial compression ratio of columns. For avoiding the randomness of seismic waveselection, by applying the analysis method of forced displacement, stress performance of the structure with joints in thelower part of a single building and the roof connected as a whole was studied, and it is proved that the most unfavorableseismic wave conditions can be enveloped. For increasing the clear height of the building, through the joint stress analysisof curtain wall columns and roof steel beams, it is proved that the roof single span structure can be changed into a multispan structure, and the span height ratio of the beam members can reach more than 50. In order to ensure the comfort ofthe multi-storey and large-span boarding bridge, the correctness of the design parameters was proved by the pedestrian loadexcitation test.
Keywords: Hangzhou Xiaoshan International Airport; large-span structure; large cantilevered structure; mutualinterference increase coefficient; comfort; pedestrian load excitation
