... is the Temse bridge across the river Scheldt in Belgium. This bridge is part of an important transport route for heavy lorries to the port of Antwerp. The Temse bridge was built in 1955. Initially, the mov- able part had an aluminium deck plate. After many repairs, the movable part however was rebuilt in 1994 using a steel orthotropic plated deck (Fig. ...

A Network Arch Bridge is designed and studied. The hangers arrangement and the stability of the arches are analysed. Possible solutions with respect to spans, materials and deck cross-section typology are presented and succinctly discussed. The finite element model created for the main bridge is described. The influence of the hangers arrangement o...
In this paper, the fatigue design of rails in the transition from bridge to abutment is examined. The current fatigue design of rail systems is carried out with simplifying assumptions concerning the stresses in the rail. Thus, the determination of a fatigue endurance limit is done with stresses based on the Smith-Diagram. By applying this means of...
In actual production practice, blunt block structures usually exist in multiple forms simultaneously, such as buildings, bridges, and offshore platforms. Flow around multi-cylinder structures is often accompanied by complex phenomena, including separation and reattachment of shear layers, vortex-structure interactions, and the evolution of wake vor...
ratio on the constant amplitude fatigue limit (CAFL). However, fatigue test data show that there is a substantial influence of the
stress ratio on the CAFL. In this study, a simple fatigue design criterion for riveted members is proposed taking into account the
effect of stress ratio. The applied method is based on the constant life diagram (CLD) m...

The development of a generalised framework for assessing bridge life-cycle performance and cost, with emphasis on analysis, prediction, optimisation and decision-making under uncertainty, is briefly addressed. The central issue underlying the importance of the life-cycle approach to bridge engineering is the need for a rational basis for making informed decisions regarding design, construction, inspection, monitoring, maintenance, repair, rehabilitation, replacement and management of bridges under uncertainty which is carried out by using multi-objective optimisation procedures that balance conflicting criteria such as performance and cost. A number of significant developments are summarised, including time-variant reliability, risk, resilience, and sustainability of bridges, bridge transportation networks and interdependent infrastructure systems. Furthermore, the effects of climate change on the probabilistic life-cycle performance assessment of highway bridges are addressed. Moreover, integration of SHM and updating in bridge management and probabilistic life-cycle optimisation considering multi-attribute utility and risk attitudes are presented.
Existing bridges represents strategic components of infrastructural nets, actually matching with an increasing traffic flow. Despite their increasing age, and even if subjected to an increasing heavy traffic, these nets stands generally in a good structural health. At the same time, prolonged out of service due to structural problems are rare. Nevertheless, it is important to highlight the major causes of degradation reported in bridges, to achieve an adequate maintenance and design. In particular, the design stage should be aware that new structures should ensure growing capacity and structural performance along its lifetime. Bridge assessment help in this way: it is a relatively recent bridge engineering science growing faster, as the amount of resources needed for the complete repair of existing bridges is absolutely impossibile to be retrieved for the managing authorities. It is a scientific based and technical procedure, mainly not coded, aiming at producing evidences on the bridge health, of the structural reliability, and of the suggested procedure to prolong its life. The purpose of this study, is to provide a review of recent studies and research accomplishments in the field of bridge assessment, management and life cycle analysis
