Replacement of the existing cables is one component of the renovation works necessary to extend the design life of this large steel bridge by at least 30 years.

The new cables also need to fit within the existing bridges and the detailing needs to be adapted to the existing situation. Experience of the design of cable supported structures, the knowledge of cables, the methods of installation, the design of specialized temporary works and detailing around anchorages needs to be combined. This article will cover the different aspects of cable replacement, the experience of suspension bridges and cable-stayed bridges and will describe two case studies in North America.

It requires renovation to provide a solution for fatigue damage in the deck through application of a high strength concrete overlay. The clearance for navigation traffic is also to be increased and a porous asphalt overlay will be applied. This paper elaborates on the assessment and strengthening design of the steel box girder, which sees a 50% increase in dead load due to the applied overlays as well as increased live loading. An effective strengthening concept was found by stiffening of panels and adding two lines of vertical bracing in the box girder. Both activate more of the existing steel in the box girder, and the bracing provides a new shear path. Increased navigation clearance is obtained by jacking the bridge over its nine pier supports, so that a 1250mm raise in midspan is achieved gradually.

Such plain pylon bodies prompt the use of saddle to guide a continuous tendon across, or, alternatively, push the connection of the stay cable on the outside, using structural tensile components such as steel links, to obtain the transfer of the stay cable loads to the pylons.Toe multiaxial loading of the stay cable on the pylon connection, as well as functional needs associated to stay cable operations, compelled establishment of numerous criteria to achieve the design of such devices.Today, engineers have gained experience in the design, manufacture and installation...

Research paper thumbnail of Crack growth prediction of deck plate-stiffener joints in orthotropic steel bridge decks

IABSE Conference, Rotterdam 2013: Assessment, Upgrading and Refurbishment of Infrastructures, 2013

Due to the typical detailing applied as around 1970, a significant number of deck structures constructed in that period suffer from fatigue damage. In many countries cracks have been detected, in particular in the weld between the deck plate and the trapezoidal stiffener. These cracks tend to grow relatively slowly, but are difficult to detect at an early stage because they initiate from inside the trapezoidal stiffener.This paper presents a model with which the growth of these cracks can be predicted. The model is aimed at the growth rate prediction of through-thickness cracks that can be detected by visual inspection, but that do not have a risk of fracture, which would affect the traffic safety. Stresses are extracted from a detailed finite element model of the entire deck. A second, local finite element model including the crack is used as the basis of a fracture mechanics model. The growth rate determined with the mode...

This method has been further developed by using an innovative Prefabricated Ultra High Performance Fibre Reinforced Concrete/Béton Spécial Industriel ® (UHPFRC/BSI ® ) Slab solution. The prefabricated slabs can be installed faster than pouring and curing concrete in-situ. Also, if a deck plate repair is required, it can be made post deck strengthening using traditional welding methods as the presented solution is less sensitive to heat than the in-situ HSC solution, which utilises a heat sensitive Epoxy-Bauxite bonding layer between the concrete and steel deck. The presented solution has been used by Eiffage on one bridge in France (Pont de Illzach, Alsace) and it has been developed for the Ewijk Bridge. This development, documented in this paper, constitutes a significant change in terms of bridge typology and loading.
