Camara A, Nguyen K, Ruiz-Teran AM, et al., 2014, Serviceability limit state of vibrations in under-deck cable-stayed bridges accounting for vehicle-structure interaction, Engineering Structures, Vol: 61, Pages: 61-72, ISSN: 0141-0296
Verification of the serviceability limit state of vibrations due to traffic live loads can be neglected in conventional types of concrete road bridges but becomes critical in the design of slender structures like under-deck cable-stayed bridges. The novelty of the work presented in this article is that an innovative vehicle-bridge interaction model is employed, in which realistic wheel dimensions of heavy trucks, road roughness profiles and the cross slope of the road are considered in nonlinear dynamic analyses of detailed three-dimensional finite element models. An extensive parametric study is conducted to explore the influence of the bridge parameters such as the longitudinal and transverse cable arrangement and the support conditions, in addition to the load modelling, road quality, the wheel size, the transverse road slope and the vehicle position and speed on the response of under-deck cable-stayed bridges. It has been observed that the vibrations perceived by pedestrians can be effectively reduced by concentrating the cable-system below the deck at the bridge centreline. The Fourier amplitude spectrum of the acceleration at critical positions along the deck proved that the response of under-deck cable-stayed bridges is not dominated only by contributions at the fundamental mode and, consequently, the conventional deflection-based methods are not valid to assess the users comfort. Instead, Vehicle-Bridge Interaction analyses are recommended for detailed design, considering the wheel dimensions if the pavement quality is bad and/or if the wheel radius is large. Finally, we verify through multiple approaches that the comfort of pedestrian users is more critical than that of vehicle users. However, the comfort of vehicle users is shown to be significantly affected when the road quality is poor.

Under‐deck cable‐stayed bridges are very effective structural systems for which the strong contribution of the stay cables under live loading allows for the design of very slender decks for persistent and transient loading scenarios. Their behaviour when subjected to seismic excitation is investigated herein and a set of design criteria are presented that relate to the type and arrangement of bearings, the number and configuration of struts, and the transverse distribution of stay cables. The nonlinear behaviour of these bridges when subject to both near‐field and far‐field accelerograms has been thoroughly investigated through the use of incremental dynamic analyses. An intensity measure that reflects the pertinent contributions to response when several vibration modes are activated was proposed and is shown to be effective for the analysis of this structural type. The under‐deck cable‐stay system contributes in a very positive manner to reducing the response when the bridges are subject to very strong seismic excitation. For such scenarios, the reduction in the stiffness of the deck because of crack formation, when prestressed concrete decks are used, mobilises the cable system and enhances the overall performance of the system. Sets of natural accelerograms that are compliant with the prescriptions of Eurocode 8 were also applied to propose a set of design criteria for this bridge type in areas prone to earthquakes. Particular attention is given to outlining the optimal strategies for the deployment of bearings.

Under-deck, cable-stayed bridges and combined cable-stayed bridges constitute two innovative bridge types that have been designed and built on relatively few occasions over the last 30 years, in most cases by renowned structural engineers, such as Leonhardt, Schlaich, Virlogeux, Manterola, Robertson and Cremer. In these bridge types, the stay cables have unconventional layouts: either below the deck, in the case of under-deck cable-stayed bridges, or above and below the deck, in the case of combined cable-stayed bridges. In this paper, a general and critical overview of the current state-of-the-art is outlined, addressing issues related to proposals, built bridges and research. Significant attention is paid to their highly efficient structural behaviour and unconventional design criteria, both of which lead to a significant reduction in the amount of required materials, in comparison with conventional bridges without stay cables, and thus allow for sustainable design. Other advantages of these bridges, such as multiple construction possibilities, strong aesthetic characteristics and their broad range of potential applications, are also stressed.
