Deformation capacity evaluation for flat slab seismic design

Aurelio Muttoni, António Manuel Pinho Ramos, Lorenzo Martinelli, Andri Setiawan

In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of the slab around the column (punching failure) is typically the governing failure mode which limits the deformation capacity and can potentially lead to ...

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 ...

Influence of sustained loading on resistance and deformation capacity of reinforced concrete members in compression

Aurelio Muttoni, Miguel Fernández Ruiz, Xhemsi Malja

As acknowledged explicitly or implicitly in most of current design codes, a high level of sustained loading has a detrimental effect on the concrete compressive strength. However, its beneficial effect in terms of deformation capacity is neglected in most ...

Punching of edge columns with and without shear reinforcement: an experimental investigation

Aurelio Muttoni, Diego Hernández Fraile, Andri Setiawan, Júlia Borges Dos Santos

Most research efforts in the past related to the punching resistance of reinforced concrete slabs have concentrated on the response of internal slab-column connections, where significant advances in the state-of-the-art have been performed. Other than inte ...

Seismic Performance of Strengthened Slab-Column Connections in a Full-Scale Test

Aurelio Muttoni, António Manuel Pinho Ramos

Strengthening of flat slab-column connections to resist imposed lateral drifts is often required for older reinforced concrete structures in which the flat slabs were typically designed to resist gravity load only or have been designed for less stringent r ...

Design of slender and squat reinforced concrete members with shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Marko Pejatovic

As proposed in several design standards for structural concrete, including Eurocode 2 (EN:1992-1-1:2004) and fib's Model Code 2010, the shear design of slender members with shear reinforcement can be performed by means of consistent models based on suitabl ...

Experimental investigation of dowel action using advanced measurement techniques

Aurelio Muttoni, Marko Pejatovic

Existing shear-cracked structures need to be reliably verified in order to avoid redundant interventions. Code provisions often raise shear safety and/or fatigue life concerns of the reinforcement subjected to stress concentrations due to cyclic dowel acti ...

Anchorage of shear reinforcement in beams and slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Frédéric Monney, Qianhui Yu

Anchorage of shear reinforcement, such as links or stirrups, can be performed by providing hooks, bends or heads at their ends, by welding transverse reinforcement or by closing open stirrups with pins. Hooks and bends, also used to enhance the anchorage o ...

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 ...

Long anchorage resistance of reinforcement bars derived from local bond-slip relationships for good and poor bond conditions

Aurelio Muttoni, Enrique Corres Sojo

The fib Model Code 2010 (MC2010) contains a semi-empirical formulation for the local bond-slip relationship for both pull-out and splitting failure modes (derived from short pull-out tests), as well as a semi-empirical formulation of the steel stress that ...

Concrete compressive strength: From material characterization to a structural value

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

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 ...

Testing of a full-scale flat slab building for gravity and lateral loads

Aurelio Muttoni, António Manuel Pinho Ramos

Full-scale testing of a two-storey flat slab structure is reported, undertaken in the SlabSTRESS research project; the construction and testing were planned and carried out at the ELSA laboratory of the European Commission's Joint Research Centre. The dime ...

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 ...

Spalling of concrete cover induced by reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

This paper investigates the phenomenon of cover spalling in reinforced concrete induced by bond or by the action of an inner pressure. This research is based on an experimental programme comprising a series of bond tests and a series of tests with inner-pr ...

The influence of casting position and disturbance induced by reinforcement on the structural concrete strength

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

It is well known that control specimens used to assess the concrete strength of new structures have different casting and curing conditions than those of actual structures. Notably, after pouring of the concrete and before its hardening, a number of phenom ...

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 ...
