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 multi-storey buildings, columns are usually not continuous through the slabs to enhance ease of construction. Consequently, in slab–column joints, slabs have to carry column loads in addition to the shear and bending moments due to loads applied to the ...
Punching shear of reinforced concrete flat slabs supported on columns is a failure mode in which the slab fractures around the column. This type of failure is sudden and can be catastrophic in nature. Punching shear generally governs the ultimate limit sta ...
Design methods for shear in reinforced concrete structures typically rely upon shear transfer through cracks, which depends upon the crack opening and sliding displacements and the roughness of the crack surfaces. The effectiveness of shear transfer throug ...
Reinforced concrete flat slabs are extensively used in buildings and parking garages. Their design is governed by deflection at the serviceability limit state and punching shear at the ultimate limit state. When no punching shear reinforcement is provided, ...
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 ...
Over the past century, the use of flat slabs in buildings and especially in parking garages has been growing as it is an economic and efficient solution. Flat slabs are easy to build and have, through their smaller depth, an economical and architectural ad ...
It is recognized that most damage to reinforced concrete structures is caused by insufficient durability rather than by low strength. In most cases, the quality and thickness of the cover concrete (covercrete) determine the service life of the structure. S ...
The traditional approach of codes of practice for estimating the punching strength of shear-reinforced flat slabs is based on the assumption that concrete carries a fraction of the applied load at ultimate while the rest of the load is carried by the shear ...
This paper presents a model to predict the shear resistance of the unreinforced lightweight concrete core of a recently developed hybrid sandwich concept for bridge decks. The sandwich skins consist of a fiber-reinforced polymer (FRP) composite sheet for t ...
The present research improves the experimental and theoretical knowledge on the behaviour of structural elements made of ultra high performance fibre reinforced concrete (UHPFRC) with ordinary reinforcement. UHPFRC is a recently developed material with muc ...
