Abstract

Abstract: Swivel technique has been vividly recognized and generally adopted for the T-rigid frame bridge in practice, and this has been achieved by tensioning the prestressed stranding via the ball hinge at the centre of the rigid frame bridge. Although the technique has been adopted and used, very limited study has been devoted to the feasibility of synchronous swivel for double-swing synchronous swivel T-rigid frame bridges to date. This study aims at analysing the construction control of a synchronous swivel T-rigid frame bridge with the self-weight of 12, 000 ton for each wing, and providing simplified procedures to determine the unbalanced weight and friction coefficient of the rotating bridge. This study will provide guidance for the future similar projects.
