AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In this paper, several probabilistic models for evaluating the fatigue performance of post-weld treated tubular bridge structures are briefly described. The application of the models is then demonstrated on a full-scale example bridge. Under realistic traf ...
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 reports on the composite action developed between pultruded FRP bridge deck systems and the supporting main girders for road bridges. Presented are requirements that an FRP deck must satisfy in order to function as part of the upper chord of the ...
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 ...
This paper describes the behavior of hybrid girders consisting of fiber-reinforced polymer (FRP) bridge decks adhesively connected to steel main girders. Two large-scale girders were experimentally investigated at the serviceability and ultimate limit stat ...
Fatigue experiments on adhesively connected pultruded profiles were performed in a laboratory environment. The first objective was to determine if fatigue limits exist and if so, how their magnitude is compared to real shear stress amplitudes in GFRP bridg ...
Following ICOM’s participation in the redaction of a new recommendation for the evaluation of existing railway-bridges, in collaboration with the SBB/CFF, new questions have been raised. Among those, the influence of a welded longitudinal attachment ends s ...
A process of self-assembly induced by electro-chemical etching was used to produce nano and micrometer scale pyramid-structures on (100) surfaces of gold. The pyramids grew in a self-similar fashion with the facets aligned in (114) plane. Using the unique ...
Axial tension-tension fatigue experiments were performed on pultruded glass fiber reinforced polymer (GFRP) plates in a laboratory environment. Different full-scale specimen shapes were examined: plate strips as-delivered, plate strips with tabs and plates ...
Rehabilitation projects aim to enhance durability and to ensure structural safety. Ultra-High Per-formance Fibre Reinforced Concretes (UHPFRC) may fulfil these requirements when used as conservation materials. The structural response of composite UHPFRC-c ...
