Influence of Fatigue Loading in Shear Failures of Reinforced Concrete Members without Transverse Reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Francisco Manuel Maciel Natário, Juan Manuel Gallego Martín

Shear fatigue of reinforced concrete members without transverse reinforcement has been observed to be potentially governing for the strength of some structural members subjected to large live loads of repetitive nature (as traffic, wind or wave actions). A ...

Analogy between Sustained Loading and Strain Rate Effects on the Nonlinear Creep Response of Concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

This paper investigates the uniaxial compression behaviour of concrete under different strain rates and its relation to sustained loading. The aim is to observe the strain rate effect on the pre- and post-peak behaviour of concrete. In particular, the deve ...

Limit Analysis for Punching Shear Design of Compact Slabs and Footings

Aurelio Muttoni, Miguel Fernández Ruiz, Duarte Miguel Viúla Faria, João Tiago Ramos Bernardo de Santa Rita Simões

In this paper, the kinematical theorem of limit analysis is used to obtain the governing failure mechanisms and the corresponding failure load of reinforced concrete footings without transverse reinforcement. To that purpose, a Mohr-Coulomb yield criterion ...

Shear failures in reinforced concrete members without transverse reinforcement: An analysis of the critical shear crack development on the basis of test results

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

Shear in concrete members without transverse reinforcement can be carried by various potential sheartransfer actions, whose activation depends much on the actual cracking pattern and kinematics at failure. Failures can occur in a progressive manner (at the ...

Shear-Fatigue Behaviour of RC Cantilever Bridge Deck Slabs under Concentrated Loads

Aurelio Muttoni, Miguel Fernández Ruiz, Francisco Manuel Maciel Natário

Shear has been observed to be the governing failure mode of RC cantilever deck slabs of bridges without shear reinforcement when subjected to concentrated loads of heavy vehicles. This observation has been verified experimentally for a quasi-static applica ...

Shear strength of RC slabs under concentrated loads near clamped linear supports

Aurelio Muttoni, Miguel Fernández Ruiz, Francisco Manuel Maciel Natário

Reinforced concrete slabs without shear reinforcement subjected to concentrated loads near linear sup- ports are usually designed or assessed in shear using design provisions that have been calibrated on the basis of tests on one-way slabs or beams with re ...

Stress Fields for the analysis of the faillure load and cracking state of dapped-end beams (Aplicación de modelos de campos de tensiones para el análisis en servicio y rotura de apoyos a media madera)

Aurelio Muttoni, Miguel Fernández Ruiz, Jaime Mata Falcon

The automatic generation of elastic-plastic stress fields (EPSF) for structural concrete members by means of the finite element method has been demonstrated as a suitable approach for the design and assessment of D regions. This methodology allows accounti ...

How simple can nonlinear finite element modelling be for structural concrete?

Aurelio Muttoni, Miguel Fernández Ruiz, Galina Argirova

This paper discusses on the required level of simplicity for suitable modelling of structural concrete. Traditional equilibrium-based approaches (as strut-and-tie models) are too coarse in some cases, as they account for the cracking state of concrete in a ...

Influence of prestressing on the punching strength of post-tensioned slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Thibault Clément, António Manuel Pinho Ramos

Previous researches on punching of post-tensioned slabs have shown a number of phenomena significantly influencing their strength and behaviour. However, no general agreement is yet found on a physical theory (either in codes of practice or in design model ...

Shear Strength of Arch-Shaped Members without Transverse Reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Stefano Campana

Arch-shaped members are used in many reinforced concrete structures such as tunnels, bridges, silos, or offshore constructions. They are generally designed to carry significant axial forces, and, in most cases, are not provided with transverse reinforcemen ...

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 ...

Punching of flat slabs supported on rectangular columns

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

This paper investigates the structural behaviour of RC flat slabs supported on rectangular interior columns and the influence of the loading conditions (one or two-way bending) on their punching shear strength. The punching shear strength of slabs at recta ...

Experimental investigation on seismic behaviour of slab-column connections

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Code design of slab-column connections to resist seismically induced drifts is currently based on empirical relationships for both moment and deformation capacity. The results of tests on slabcolumn connections are however sensitive to the conception of th ...

Strength of arch-shaped members in bending and shear

Aurelio Muttoni, Miguel Fernández Ruiz, Stefano Campana

Arch-shaped members are widely used for construction of tunnels, bridges, silos and shells. These members are not typically provided with transverse reinforcement and may thus have a brittle behaviour at failure. When subjected to bending or shear, traditi ...

On the efficiency of flat slabs strengthening against punching using externally bonded fibre reinforced polymers

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul, António Manuel Pinho Ramos, Duarte Miguel Viúla Faria

One possibility for strengthening existing flat slabs consists on gluing fibre reinforced polymers (FRPs) at the concrete surface. When applied on top of slab–column connections, this technique allows increasing the flexural stiffness and strength of the s ...

Mechanical Model for flexural behaviour of slab-column connections under seismically induced deformations

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported on columns are one of the most widely used structural systems for office and industrial buildings. In regions of medium to high seismic risk RC walls are typically added as lateral force resisting system and to ...

Punching resistance and flexural behaviour of continuous flat slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

The punching resistance of actual reinforced concrete flat slabs is potentially influenced by the compressive membrane action, which may significantly increase their resistance compared to isolated laboratory specimens. However, design codes have been deve ...

Interaction between in-plane shear forces and transverse bending moments in concrete bridge webs

Aurelio Muttoni, Miguel Fernández Ruiz, Marie-Rose Backes

This paper investigates a reliable design approach for reinforced concrete panels subjected to the combined action of in-plane shear and out-of-plane bending moments, which develop in webs of boxgirder bridges and similar structures. Neglecting this intera ...
