Abstract

Abstract

Based on the wind-tunnel test of rigid model of Jilin Railway Station,the mean and fluctuating pressure coefficients,the lift coefficients of the roof were presented and discussed with and without the surrounding buildings. Analyses of the characteristics of the local shape coefficient distributions and wind-induced responses were conducted. It was found that negative pressures (suctions) occurred on the railway station roof in general,the values of the lift coefficients of the roof were negative,and high negative pressure coefficients occurred on the eaves,cantilevered roof and the bulge part of the roof on the main station building. Relatively smaller suctions occurred on the platform awnings of the station because of open surrounding configurations there. The surrounding buildings have some shielding effect on the local shape coefficients of the roof,but can not ignore the situation where they are increased in some areas. Wind-induced responses were significant on the corner of platform awnings,cantilevered roof and the bulge part of the roof. The conclusions obtained from this study are expected to be useful in the wind-resistant design of long-span steel roof structures with complex shapes.
