Design of Roof Steel Structure of New Guangzhou Railway Station

摘要

Bridge-station combined structure system is applied in New Guangzhou Railway Station, which is the main building of Guangzhou Railway Center. The plan dimension is about 525m X 586m and the area is 0. 56 million square me ters. There is one floor underground and three floors overground. The ground floor is parking. The second floor is railway platform, which consist of one dimensional prestress reinforced concrete frame structure and 64m-span arc structure. The third floor is waiting room, which consist of prestress reinforced concrete frame structure, and the columns are supported on bridges or piers. The plan dimension of main station roof consisting of longspan prestress spatial system is 476mX 222m, which is separated with canopy roof by aseismic joint. There are 9 aseismic joints in second floor and 2 in third floor. The mass and stiffness are greatly different in different floors. The structure sys tem character, interrelation and arrangement is thoroughly introduced.
