Reinforced concrete bridge deck slabs without shear reinforcement can be subjected to concentrated or distributed loads of important magnitude. Under these loads their structural response is not always ductile. In particular under concentrated loads their ...
In the design of recently constructed steel-concrete composite bridges using hollow section trusses for the main load carrying structure, the fatigue verification of the tubular truss joints has been a main issue. Recent research on the fatigue behaviour o ...
Due to their aesthetic and structural advantages, tubular space truss structures are enjoying increasing popularity in modern bridge construction. The use of cast steel nodes for the joints between the circular hollow section members is also becoming incre ...
Le projet de recherche Evaluation des systèmes existants pour le suivi à long terme des déformations des ponts a été initié dans le but de préparer sous forme condensée une présentation et une évaluation des systèmes de mesure existants pour le suivi à lon ...
Herein, a probabilistic model for predicting the effect of post-weld treatment on the fatigue performance of the welded joints in tubular truss bridges is described. Specifically, a probabilistic LEFM-based model is first developed for the fatigue analysis ...
Up until today reinforced concrete has been used in most cases for the manufacturing of bridge decks. Depending on the quality of the work carried out, defects can already occur after only a few years. These defects mostly appear in the form of corrosion o ...

This paper describes the quasi-static and fatigue performance of hybrid bridge girders composed of cellular FRP bridge decks and steel girders. The FRP bridge deck is connected adhesively to the steel girders and acts as the top chord of the hybrid section ...
Dynamic experiments were conducted on an all-FRP composite pedestrian bridge. The structure was excited by impact and human-induced vibrations. The peak-picking method and stochastic subspace identification method were used to extract structural dynamic ch ...
So-called “non-load bearing” parts of (railway) bridges increase the stiffness and decrease the stresses in short span bridge structures. The rail track, consisting of ballast, sleepers and rails, has a non-linear behaviour and its rigidity depends on the ...
