This paper introduces the aerodynamic challenges of ultra long span cable stayed bridges with a main span exceeding 1,200m and provides technical solutions based on the specimen design of a 1,400m main span partially earth anchored cable stayed bridge. An innovative tie cable technology is introduced which makes the construction feasible and allows a 30% reduction in the steel deck quantities compared to a bridge built by the traditional cantilever method. |
