Assessing punching shear failure in reinforced concrete flat slabs subjected to localised impact loading

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar

Reinforced concrete flat slab structures are used widely in construction projects due to their economic and functional advantages. Punching shear failure in such structures can have catastrophic effects in the case of, for example, multi-storey framed stru ...

Concrete bridge deck slabs strengthened with UHPFRC

Eugen Brühwiler, Maléna Bastien Masse

An original concept is presented for the durable rehabilitation of concrete bridge deck slabs. The main idea is to add a layer of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) with steel reinforcing bars over the concrete slab to create a compo ...

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 ...

Experimental Investigation on Punching Strength and Deformation Capacity of Shear-Reinforced Slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Stefan Lips

This paper presents the results of an extensive experimental campaign on 16 flat-slab specimens with and without punching shear reinforcement. The tests aimed to investigate the influence of a set of mechanical and geometrical parameters on the punching sh ...

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 ...

New Fe-immobilized natural bentonite plate used as photo-Fenton catalyst for organic pollutant degradation

César Pulgarin

Novel photo-Fenton catalysts were prepared by immobilizing iron species on commercial bentonite plates via two methods: (1) ion exchange reaction (Fe3+ vs. Na+) by aqueous suspension powder-clay/FeCl3 followed by plate preparation, and (2) forced hydrolysi ...

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, ...

Experimental investigation of reinforced concrete slabs with punching shear reinforcement

Aurelio Muttoni, Stefan Lips

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 ...

Structural Response of Reinforced UHPFRC and RC Composite Members

Cornelius Oesterlee

Ultra High-Performance Fibre-Reinforced Concrete (UHPFRC) combines high strength, deformation capacity and low permeability. This makes UHPFRC particularly suitable as a strengthening and protective layer for application to existing reinforced concrete str ...

Influence of Shear on Rotation Capacity of Reinforced Concrete Members Without Shear Reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Rui Vaz Rodrigues

The influence of shear on the rotation capacity of one-way slabs without shear reinforcement is investigated in this paper by means of an experimental study. The experimental program consisted of 11 slab strips 8400 mm (331 in.) long and 450 mm (17.7 in.) ...
