Characterization of shear deformations in reinforced concrete members without shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone, Andri Setiawan

The load-carrying capacity of many reinforced concrete structures is governed by shear failures, occurring before reaching the flexural capacity of the member. For redundant systems, such as slabs subjected to concentrated loads, local shear failures (typi ...

The mechanics of shear failures in RC slabs based on refined measurements

Raffaele Cantone

Reinforced concrete planar members, as slabs and shells, are structural elements commonly used in the construction technique, which are typically designed without the arrangement of shear reinforcement. Despite the fact that this solution allows for fast a ...

Shear force redistributions and resistance of slabs and wide beams

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Redistribution of shear forces in reinforced concrete members without shear reinforcement is a key aspect for the assessment of the shear capacity of wide beams and slabs. Such redistributions are due to the nonlinear response of reinforced concrete (both ...

A detailed view on the rebar–to–concrete interaction based on refined measurement techniques

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Simplified assumptions have traditionally been made on the rebar–to–concrete interaction in structural concrete to calculate the stress state in rebars. Such assumptions typically consider a uniform stress state in the reinforcement at a given cross sectio ...

Enhancing Punching Strength and Deformation Capacity of Flat Slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Punching reinforcement systems have significantly developed in recent years as they allow enhancing the punching resistance of slab-column connections as well as their deformation capacity. These systems, with varying geometry and layout, normally consist ...

Shell Modelling Strategies for the Assessment of Punching Shear Resistance of Continuous Slabs

Aurelio Muttoni, Raffaele Cantone, Beatrice Belletti

The punching shear resistance formulation provided by Model Code 2010 is calibrated on the basis of experimental tests on isolated slabs supported on columns. According to Level of Approximation approach, several quantities are required for the design punc ...

Combining finite element analyses and mechanical models for the assessment of reinforced concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

The influence of the level of deformation of the flexural reinforcement on the punching strength is well-established and mechanically founded since the pioneer works of Kinnunen and Nylander in the 1960’s. In code provisions, this influence is sometimes re ...

Compressive Membrane Action Effects on Punching Strength of Flat RC Slabs

Aurelio Muttoni, Raffaele Cantone, Beatrice Belletti, Luca Manelli

The design of reinforced concrete flat slabs in practice can be governed at failure by punching shear close to concentrated loads or columns. Punching shear resistance formulations provided by codes are calibrated on the basis of experimental tests on isol ...

Approaches for suitable modelling and strength prediction of reinforced concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone, Beatrice Belletti

Despite the advances on the understanding and modelling of shear and punching shear failures, the application of actual design models to some stations remains still complex. In addition, other significant phenomena such as compressive membrane action and m ...

Shear strength evaluation of RC bridge deck slabs according to CSCT with multi – layered shell elements and PARC_CL Crack Model

Aurelio Muttoni, Raffaele Cantone, Beatrice Belletti

The shear resistance of RC slabs without shear reinforcement subjected to concentrated loads near linear support is usually calibrated on the base of tests on one – way slabs with rectangular cross section. However, the actual behavior of slabs subjected t ...
