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.
FRP bridge decks offer several advantages compared with conventional concrete bridge decks, particularly their much lower weight, but also their resistance against corrosion as well as easier installation and maintenance. The poorly conceived methods avail ...
Punching of flat slabs without transverse reinforcement has mostly been investigated in the past for slabs with equal reinforcement ratios in the two directions and loaded under axis-symmetrical conditions. However, in practice, slab bridges as well as man ...
The concept of confined concrete has been widely accepted throughout the structural engineering field, such as the spiral, steel tube, or carbon fiber composite shell confined concrete, etc. In the present study, this concept has not only been used in the ...

Desiccation cracking of soils is of great importance to geotechnical and geoenvironmental engineering as it affects the soil physical integrity. Yet the mechanisms of drying cracking in soils, and the ways to control or avoid it, are still elusive. This pa ...

Strut and tie models and stress fields are methods that can be used for the dimensioning and detailing of reinforced and prestressed concrete structures as well as for the check of existing ones. This paper presents an innovative approach towards the autom ...

Ultra High Performances Fibre Reinforced Concretes (UHPFRC) are characterised by an ex-tremely low permeability and outstanding mechanical properties. These characteristics make UHPFRC suitable for locally “harden” reinforced concrete structures subjected ...
Computer-aided approaches for the efficient development of suitable stress fields are useful tools for the structural design of concrete structures. The paper describes a new procedure that is used within a previously proposed approach for the automatic ge ...

Ultra High Performances Fibre Reinforced Concretes (UHPFRC) are characterised by an extremely low permeability and outstanding mechanical properties. These characteristics make UHPFRC suitable for locally “harden” reinforced concrete structures subjected t ...
The stress field method is a technique based on the lower-bound theorem of plasticity that can be used for dimensioning, detailing and checking of structural concrete elements. Its use has been traditionally associated with the assumption of simplified (ri ...
The deterioration of reinforced concrete structures and the associated rehabilitation work represent an economic cost of premier importance. In Switzerland, the structural maintenance expenditures amount to 40% to 65% of the initial construction cost (over ...
