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 ...

Concrete compressive strength: From material characterization to a structural value

Aurelio Muttoni, Miguel Fernández Ruiz, Qianhui Yu, Francesco Rafael Alberto Moccia

The compressive resistance of concrete in new structures is usually characterized on the basis of tests performed on concrete cylinders or cubes under relatively rapid loading conditions. Although efficient for material characterization, these tests do not ...

The influence of the kinematics of rough surface engagement on the transfer of forces in cracked concrete

Miguel Fernández Ruiz

One of the most instrumental aspects governing the response of structural concrete at ultimate limit state refers to the possibility of developing smeared cracking patterns within a member (associated normally to the presence of sufficient reinforcement fo ...

The influence of transverse reinforcement and yielding of flexural reinforcement on the shear-transfer actions of RC members

Miguel Fernández Ruiz

The assessment of the shear strength of reinforced concrete beams with and without shear reinforcement is investigated in this paper on the basis of the contribution of the various potential shear-transfer actions. To that aim, a comprehensive experimental ...

An interlocking approach for the rebar-to-concrete contact in bond

Aurelio Muttoni, Miguel Fernández Ruiz, Max Tirassa

The bond response of deformed bars in structural concrete is a phenomenon governed, to a large extent, by the rib-to-concrete contact and interaction, with contact forces depending on both material properties and the kinematics between the contact surfaces ...

A consistent safety format and design approach for brittle systems and application to textile reinforced concrete structures

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri, Qianhui Yu

Design and verification of structures in modern codes of practice account for a safety format, ensuring that the probability of failure does not exceed a given threshold. Although specific safety formats are proposed in some cases for special types of stru ...

A mechanical approach for the maximum punching resistance of shear-reinforced slab-column connections

Aurelio Muttoni, Miguel Fernández Ruiz, João Tiago Ramos Bernardo de Santa Rita Simões, Diego Hernández Fraile

The use of punching shear reinforcement is currently considered as one of the most convenient practices to enhance the punching shear strength and deformation capacity of slab-column connections in flat slabs. Intensive research has been performed in the l ...

Design against splitting failures in reinforced concrete due to concentrated forces and minimum bend diameter of reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Frédéric Monney

Plastic bending of reinforcement bars against mandrels is the usual procedure to provide bends and hooks for steel reinforcement bars. Minimum mandrel diameters are usually given in to codes of practice, depending on the type of detail and diameter of the ...

Casting position effects on bond performance of reinforcement bars

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

The phenomena associated with the consolidation of fresh concrete (bleeding and plastic settlement) are commonly considered significant for the bond performance of reinforcement. However, rules to take care of such influence for design are not consistent a ...
