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 ...

Influence of geometric, strain and size effects on bond in structural concrete

Aurelio Muttoni, Miguel Fernández Ruiz

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 ...

Punching shear strength of R/C slabs subjected to fire

Aurelio Muttoni, Miguel Fernández Ruiz

This paper illustrates a study on the punching shear strength of reinforced concrete slabs in fire conditions. To this end, a set of experimental data on the punching strength of heated slab specimens was interpreted by adapting the well-known Critical She ...

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 ...

Assembling system between columns and a slab and construction process therefore

Aurelio Muttoni, Roberto Guidotti, Miguel Fernández Ruiz

A concrete slab assembling system comprising: -a reinforced concrete slab (1); -a supporting column (2); -a supported column (3), having a bottom-end with a reference outer diameter thereof; -an interface adaptor (10) for placement between the supported co ...

Transition Slabs of Integral Abutment Bridges

Olivier Burdet, Aurelio Muttoni, Damien Dreier

Over the past decades, an increasing number of bridges with integral abutment have been built in Switzerland. This type of bridge offers various advantages over standard bridges with abutments, equipped with expansion joints and bearings that require regul ...

Crushing and Flexural Strength of Slab-Column Joints

Aurelio Muttoni, Roberto Guidotti, Miguel Fernández Ruiz

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 ...

New provisions for punching shear in Model Code 2010 based on the Critical Shear Crack Theory

Aurelio Muttoni, Miguel Fernández Ruiz, Luca Tassinari, Juan Sagaseta Albajar

The provisions for punching shear around concentrated loads in the new Model Code 2010 (MC2010) have been updated, covering a large number of design cases such as slabs with and without transverse reinforcement, different column/slab geometries and prestre ...

Non-axis-symmetrical punching shear around internal columns of RC slabs without transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Luca Tassinari, Juan Sagaseta Albajar

Most analytical approaches and available test data for punching shear in flat slabs assume axis-symmetrical conditions, which seems realistic for representing slabs supported on columns equally spaced in both orthogonal directions. However, in practice, th ...

Behaviour and design of slab-column joints

Aurelio Muttoni, Roberto Guidotti, Miguel Fernández Ruiz

This paper presents an investigation on the behaviour and strength of slab-column joints in multystorey buildings. Such joints may develop different potential failure modes such as crushing of the concrete of the slab (due to column loading), bending or pu ...

Applications of bent-up bars as shear and integrity reinforcement in R/C slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Luca Tassinari, Stefan Lips

Bent-up bars were extensively used as shear reinforcement in beams and slabs from the first R/C developments up to the 1970’s. Their use was justified by the fact that they allowed enhanced development of the tensile reinforcement at the same time they act ...

Analytical and numerical analyses of the load-bearing capacity of retaining walls laterally supported at both ends

Laurent Vulliet, Sylvain Plumey, Vincent Labiouse, Aurelio Muttoni

This paper investigates the load-bearing capacity of a perfectly smooth retaining wall laterally supported at both ends assuming that the wall fails by the development of three plastic hinges. The study considers the case of a cohesionless elastic–perfectl ...

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 ...

Strengthening of flat slabs against punching shear using post-installed shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

A significant number of existing flat slabs currently require strengthening against punching shear for safety reasons (the increase of applied loads and deficiencies during design or construction) or to comply with more stringent code requirements. Availab ...

Performance and Design of Punching-Shear Reinforcing Systems

Aurelio Muttoni, Miguel Fernández Ruiz

Punching shear reinforcement is increasingly used in flat slabs as an effective solution to increase their strength and deformation capacity. Several punching shear reinforcing systems have been developed in the past, such as studs, stirrups or bent-up bar ...

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

Aurelio Muttoni, Rui Vaz Rodrigues, Miguel Fernández Ruiz

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.) ...
