Influence of amount of shear reinforcement and its post-yield response on the shear resistance of reinforced concrete members

Aurelio Muttoni, Miguel Fernández Ruiz, Frédéric Monney

The minimum amount of shear reinforcement to be provided in reinforced concrete members has been a topic of debate and research for decades without reaching a consensus. Defining such values is however instrumental to build in an economic manner and to saf ...

Modelling of Textile Reinforced Concrete in bending and shear with Elastic-Cracked Stress Fields

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Textile Reinforced Concrete (TRC) is emerging as a promising alternative to ordinary Reinforced Concrete for the construction of durable, lightweight and more sustainable structures, with a large potential particularly in shells and thin members. Research ...

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 ...

Verification of shear failures of cantilever bridge deck slabs subjected to concentrated loads

Aurelio Muttoni, Miguel Fernández Ruiz

Shear design and verification of bridge deck slabs subjected to concentrated loads (as those of wheels from traffic) is a topic subjected to scientific and engineering debate, where several questions remain open. Several design procedures have been propose ...

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 ...

Tensile response of textile reinforced concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Textile Reinforced Concrete (TRC) is a cementitious composite material where a carbon or glass fabric is embedded as reinforcement. The use of TRC allows building thin and light structures, with reduced concrete covers and an enhanced durability due to the ...

Design versus Assessment of Concrete Structures Using Stress Fields and Strut-and-Tie Models

Aurelio Muttoni, Miguel Fernández Ruiz, Filip Niketic

Stress fields and strut-and-tie models are widely used for design and assessment of structural concrete members. Although they are often used in the same manner for both purposes, developing suitable stress fields and strut-and-tie models for the design of ...

Model uncertainties and partial safety factors of strain-based approaches for structural concrete: Example of punching shear

Aurelio Muttoni, Qianhui Yu, João Tiago Ramos Bernardo de Santa Rita Simões

The development of mechanical models relating the state of strains and the resistance of reinforced concrete structures has become a trend in the last decades. These types of models are referred to as strain-based approaches. Since strain-based approaches ...

Assessing the compressive strength of concrete under sustained actions: From refined models to simple design expressions

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

The detrimental influence of high levels of sustained load on the compressive strength of concrete has been acknowledged and investigated since the 1950s. Despite the potential significance of this phenomenon in many situations, current design codes still ...

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 ...

From experimental evidence to mechanical modeling and design expressions: The Critical Shear Crack Theory for shear design

Aurelio Muttoni, Miguel Fernández Ruiz

Many research efforts have so far been devoted to the topic of shear design of members without transverse reinforcement since the first development in structural concrete. This has allowed a number of significant advances in the understanding of the phenom ...

Influence of Load Duration on Shear Strength of Reinforced Concrete Members

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

The significance of sustained loading on the compressive and tensile strength of concrete has been experimentally verified since the 1950s and is currently acknowledged in most design codes implicitly or explicitly. However; its influence on other potentia ...

Fibre orientation in SFRC slabs and consequences for punching shear and flexural resistance

Aurelio Muttoni

The use of steel fibre reinforced concrete (SFRC) is a well-known method for enhancing the punching and flexural resistances of flat slabs. The structural performance of SFRC elements depends significantly on the fibre distribution and orientation, which a ...

Punching tests on edge slab-column connections with refined measurements

Aurelio Muttoni, Andri Setiawan

Due to the significant shear forces developing around columns and the potential brittle failure associated, the punching capacity of flat slabs is the main concern at ultimate limit state. An effective way to understand the behaviour of slab-column connect ...

Applications of Stress Fields to Assess the Behavior and Strength of Coupling Beams subjected to Seismic Actions

Aurelio Muttoni, Miguel Fernández Ruiz

Horizontal loading due to earthquake or wind is usually the governing action for design of reinforced concrete cores in medium to tall buildings. Building cores designed to resist these actions must be dimensioned to resist tributary vertical loads and lar ...

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 ...

Experimental investigation on fatigue of concrete cantilever bridge deck slabs subjected to concentrated loads

Aurelio Muttoni, Miguel Fernández Ruiz, Francisco Manuel Maciel Natário

Shear has been observed to be often the governing failure mode of RC cantilever deck slabs of bridges without shear reinforcement subjected to concentrated loads when tested under a quasi-static application of the load. However, concentrated loads of heavy ...
