Punching shear strength of steel fibre reinforced concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Luis Felipe Maya Duque

The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional ...

Updating existing railway bridges based on monitoring data

Eugen Brühwiler, Mark Anthony Treacy, Marina Rocha Pinto Portela Nunes

Due to the important direct and indirect costs of the intervention, more detailed examination methods based on data as obtained from monitoring is suggested. This paper reports on an ongoing study to examine the fatigue safety of one standard bridge type, ...

Poinçonnement non symétrique des dalles en béton armé

Luca Tassinari

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 ...

Influence of a Prestressing Eccentricity on the Punching Shear Strength of Post-Tensioned Slab Bridges

Aurelio Muttoni, Thibault Clément

A large number of medium and small span bridges in Switzerland and in other countries are slab bridges, often prestressed, multi-span and supported by columns. Punching in such structures is typically governing at failure. So far, the knowledge of the infl ...

Post-punching behavior of reinforced concrete slabs

Yaser Mirzaei

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, ...

Shear resistance of lightweight concrete core of FRP-concrete sandwich structure

Thomas Keller, Till Vallée, Erika Schaumann

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 ...

Direct load transmission in hybrid FRP and lightweight concrete sandwich bridge deck

Thomas Keller, Till Vallée, Erika Schaumann

Direct load transmission experiments on hybrid short-span beam specimens for a novel bridge deck were performed. The sandwich construction consists of three layers: a fiber- reinforced polymer composite (FRP) sheet with T-upstands for the bottom skin, ligh ...

Hybrid FRP-lightweight concrete sandwich system for engineering structures

Erika Schaumann

Hybrid slab systems combining fiber-reinforced polymer (FRP) composites with concrete are promising load-bearing structures, and an increasing number of applications has demonstrated their high potential in terms of structural performance and durability. H ...
