SEISMIC RESPONSE ANALYSIS OF A380 HANGARAT BEIJING CAPITAL AIRPORT

摘要

Seismic response analysis of A380 hangar at capital airport is introduced in this paper. The project is located atrnthe north area of Beijing Capital International Airport in Shunyi District, Beijing. The plan dimension of thernnew hangar is 352m×110m and it will be one of the largest hangars in the world after completion. Space framernand the front truss are adopted for the roof structure and steel tube filled concrete columns and reinforcedrnconcrete column are used for the supporting system. The earthquake fortification intensity of the project is 8rndegree and the site soil classification is Class III. To study seismic response of the hangar, linear-elastic timernhistory analysis, including one-dimensional and three-dimensional earthquake inputs, have been carried out.rnAnalytical results of the one-dimensional and the three-dimensional are compared. The regularity of therndistribution of seismic internal force coefficients is presented. Moreover, multiple excitation time historyrnanalysis of the hangar is performed and the results are compared to that of the uniform support excitation. Finallyrnwhether it is necessary to perform the multi – dimensional and multiple support excitation seismic analysis of thernlong span space frame hangar is discussed. The conclusions of this study could be beneficial to earthquakernresistant analysis for long span hangar.
