| Abstract: | Based on the Jiuqu River X-arch bridge in the high-speed railway line running from Beijing to Shanghai,the first of its kind,a detailed behavioral analysis of the Jiuqu River X-arch bridge is carried out.A comparison between two different models often used in the behavioral analysis is made,and as a result,it is concluded that the planar model sometimes is reasonable. In the same time,the effects of the lateral braces in different position and of different numbers on the stabilities of the bridge as well as on its natural frequencies are discussed. |
| Keywords: | X-arch bridges tubular structures concretes Jiuqu River |
