| Abstract: | The Tianzishan bridge in Yongzhou of Hunan province is the first concrete filled steel tube truss arch bridge in the world, whose design innovation is substituting diagonal cable for the rigid diagonal rod. Building an aluminum alloy model of the bridge scaled 1:20, the dynamic characteristics of the steel pipe concrete combinatorial truss arch bridge are studied using experimental modal analysis and the influence of the cable force is also discussed. |
