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.
Cet ouvrage présente une compilation des résultats obtenus par les étudiants inscrits à l'unité d'enseignement niveau Master “Béton. Matière de construction” à l'Ecole polytechnique fédérale de Lausanne en 2013. L'unité d'enseignement est dispensée dans le ...
This paper presents experimental results which demonstrate the important, but to date little-studied influence of surfacing on the response up to failure of orthotropic GFRP bridge decking local to concentrated loading. Four bonded deck specimens were test ...
The need to maximise the lifetime of existing road bridges necessitates clear and efficient tools for engineers to perform structural safety verifications based on monitored data. This study develops methodologies for ultimate limit safety (ULS) verificati ...
An original concept is presented for the durable rehabilitation and strengthening of concrete structures. The main idea is to use Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) complemented with steel reinforcing bars to “harden” and strengthen ...
Rehabilitation of deteriorated concrete bridges is a heavy burden from the socio-economic viewpoint. Novel concepts for the rehabilitation of concrete structures must be developed. Ultra-High Performance Fibre Reinforced Concretes (UHPFRC) provide the stru ...
Im Rahmen eines europäischen Forschungsprojektes unter Federführung der École Polytechnique Fédérale de Lausanne (EPFL) wurde ein vierstöckiges Gebäude mit Mauerwerks-und Stahlbetonwänden auf dem Rütteltisch des TREES-Labors am EUCENTRE in Pavia (Italien) ...
Due to the continuous development of warm mix asphalts (WMA) as alternatives to hot mix asphalts (HMA), the choice of the most favourable mixture for a given project is not necessarily straightforward. When considering greenhouse gas (GHG) emissions and en ...
As a substantial source of greenhouse gas (GHG) emissions and energy consumption, the road construction domain has to bring a contribution to the reduction of the environmental impacts. Indeed, an important part of the energy consumption and consequently e ...
Design formulations for calculation of bond strength in structural concrete members usually include a number of parameters such as the stress acting in the reinforcement, the concrete cover and the diameter of the reinforcing bars. These parameters are act ...
Roman concrete was used as building material during Roman Imperial times for a great number of famous constructions with different functions. Well-known examples are aqueducts, for example the Pont du Gard in France and the Aqua Alexandrina in Rome, and nu ...
