“…In designing this floating bridge, however, these standards alone were not sufficient. The major technical challenges are listed below (Maruyama et al 1998a-d;Watanabe et al 1998Watanabe et al , 1999Watanabe et al , 2001aWatanabe et al , b, 2002Watanabe et al , 2003aWatanabe andUtsunomiya 2001, 2003;Watanabe 2003Watanabe , 2004: (1) Since a floating bridge is far more vulnerable to meteorological and oceanographic conditions than a conventional fixed bridge, proper environmental conditions that are suitable to the characteristics of the installation site must be met in designing the bridge. Floating structures have been one of the main focuses of investigation in various occasions, e.g., at the time of planning the Kansai International Airport, and in the ''Mega-Float Project'' led by the Ministry of Transport.…”

“…It follows from the above that the available experience regarding the performance of similar structures is very scarce. Some case studies concerning the response prediction of existing floating bridges are available, e.g., for the Nordhordland Bridge [1], the Bergsøysund Bridge [2][3][4][5], the Hood Canal Bridge [6], the William R. Bennett Floating Bridge [7], and the Yumemai Bridge [8,9]. Recently, studies regarding response prediction of planned or generic floating bridges have also emerged in literature, e.g., [10][11][12].…”

Herein, numerical predictions of the dynamic response of an existing floating pontoon bridge are compared with the measured dynamic response. Hydrodynamic coefficients that describe the fluid-structure interaction and the wave transfer functions are obtained by applying linear potential theory. The results obtained from the hydrodynamic analysis are combined with a beam model of the bridge in a finite element method (FEM) framework to enable stochastic response prediction through the power spectral density method. The standard deviations of the predicted accelerations are compared with the standard deviations of the measured accelerations, and the overall quality of the prediction model is discussed. Predictions with sea states related to the serviceability limit state (SLS) and ultimate limit state (ULS) conditions used in design of the bridge are emphasized. To investigate the behaviour more in depth, a measurement segment is chosen and predictions of the displacement response power spectral density due to excitation characterized by the recorded sea surface elevation are compared with those obtained from the corresponding response measurements. A decent agreement is obtained for both cases when using the model as it is and with waves as the only excitation source, but significant discrepancies are present, in particular, for the torsional components. By including preliminary contributions from wind action and relying on a model optimized against measured modal parameters, a satisfactory agreement is obtained. The effect on the response of an uncertain structural damping is also quantified and concluded to be significant within realistic damping levels.

“…According to the different directions of rotation, it can be divided into three types: vertical rotating construction, horizontal rotating construction and a combination of the above two constructions [1][2][3] and this study focuses on horizontal rotating construction. The horizontal rotating construction, which also can be seen as the accelerated bridge construction (ABC) method, provides the optimal urban bridge construction solution by reducing the impact on traffic, improving safety, shortening the project duration, and optimizing the project budget 4,5 .…”

The superstructure rotation method (SRM) can optimize bridge construction in terms of reducing impacts on traffic, safety, and overall budget. This paper focuses on the key scientific problems of synchronous rotation construction with large angles and takes two T-shaped rigid frame bridges of the Wuyi Expressway over the Chengdu-Kunming Railway as the engineering background. Construction technologies of this project are introduced, including the installation process of spherical hinges, the design of the traction system, and the precision control method. Finite element models of the full-bridge were established to obtain the lateral unbalanced moment of the structure and the test method of the longitudinal unbalanced moment is shown in detail. Furthermore, the key parameters of SRM are analyzed and calculated, including the derivation and modification of the existing static friction coefficient calculation formula of the spherical hinge. Based on the measured data, the accuracy of different friction coefficient prediction formulas is evaluated.
