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.

During the long service period of the transmission tower, the severe environment, material aging and fatigue effects result in the damage accumulation and resistance fading of the transmission tower, which even lead to the structural failure. In this paper, a stochastic subspace-based damage detection algorithm combined with statistical model is proposed for the damage identification of transmission tower structures through processing and analysing its vibration signals. Based on the structural modal parameters identified from the structural vibration response, the nominal modal parameters are defined. Considering that the Hankel matrixes constructed by the system observability matrix and the system output covariance matrix have the same kernel space, the damage index sensitive to the modal parameters is constructed. In the manuscript, firstly, the damage index establishment method and process of the algorithm are presented; and then the vibration data of transmission tower structure simulation under different damage conditions are obtained through numerical simulations; finally, above data are analysed to obtain the damage identification results of transmission tower. The results show that the method proposed in this work can effectively identify the local damage of transmission tower structure.
