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 ...

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 ...

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 ...

Derivation of the σ-w relationship for SFRC from prism bending tests

Aurelio Muttoni

The material characterization of steel fibre-reinforced concrete (SFRC), which is required for its implementation in design codes, should be based on nominal properties that describe its postcracking strength in tension. In the case of brittle and quasi-br ...

Behaviour and design of slab-column joints

Aurelio Muttoni, Miguel Fernández Ruiz, Roberto Guidotti

This paper presents an investigation on the behaviour and strength of slab-column joints in multystorey buildings. Such joints may develop different potential failure modes such as crushing of the concrete of the slab (due to column loading), bending or pu ...

Tensile Behaviour of reinforced ultra-high performance fiber reinforced concrete elements

Aurelio Muttoni, Dario Redaelli

Ultra-high performance fiber reinforced concrete (UHPFC) is a new class of materials that combine a very strong and dense cementicious matrix with a high fiber content. UHPFC has a very high compressive strength (in the order of 200 MPa) and a relatively l ...

Concrete shells – Towards efficient structures: Construction of an ellipsoidal concrete shell in Switzerland

Aurelio Muttoni, Miguel Fernández Ruiz

Concrete shells have been widely used in the past as economical and suitable solutions for a number of structures such as roofs, silos, cooling towers or offshore platforms. Taking advantage of their single or double curvature, bending moments and shear fo ...

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 flat slabs supported on rectangular columns

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

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 ...

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

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul, 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 ...

Estimation of the bar stress based on crack width measurements in reinforced concrete structures

Aurelio Muttoni, Enrique Corres Sojo

Estimating the stress of reinforcing bars and its variations in service conditions can be useful to determine the reserve capacity of structures or to assess the risk of fatigue in the reinforcement. This paper investigates the use crack width measurements ...

Study on Influence of Column Size and Slab Slenderness on Punching Strength

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

This paper presents the results of a systematic experimental campaign consisting of 13 symmetric punching tests on interior slab-column connections. The study focuses on the influence of varying the size of the supported area and the slenderness of the sla ...

Design of concrete structures using structural optimization based on the stress field method

Aurelio Muttoni, Miguel Fernández Ruiz, Qianhui Yu

The Elastic Plastic Stress Field method (EPSF) is a widely used tool for design and verification of structural concrete works. EPSF uses the elastic-plastic material behavior, which allows accounting for compatibility conditions and thus provides exact sol ...

Considerations on the partial safety factor format for reinforced concrete structures accounting for multiple failure modes

Aurelio Muttoni, Miguel Fernández Ruiz, Qianhui Yu

The increasing usage of nonlinear analyses for the design of reinforced concrete structures and the necessity of codes of practice to provide a consistent safety format for them is one of the challenges that new generations of codes of practice are facing. ...

Punching shear tests on compact footings with uniform soil pressure

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

Punching shear is usually the governing failure criterion for the select ion of the depth of reinforced concrete footings. Despite the fact that large experimental programmes have been performed in the past aimed at the punching strength of slender flat sl ...

Size effect in shear and punching shear failures of concrete members without transverse reinforcement: Differences between statically determinate members and redundant structures

Aurelio Muttoni, Miguel Fernández Ruiz

Large efforts have been devoted in the past to understanding size effect in shear failures of members without transverse reinforcement. Experimental works have demonstrated that increasing the size reduces the nominal shear strength provided that the failu ...

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)

Jaime Mata Falcon, Aurelio Muttoni, Miguel Fernández Ruiz

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 ...

Large Scale Tests on Bridge Slabs Cantilevers Subjected to Traffic Loads

Aurelio Muttoni, Olivier Burdet, Rui Vaz Rodrigues

To improve the reduced available experimental data on the load capacity of full scale bridge deck slabs, 3 tests on a large scale bridge cantilever (10 x 4.2 m) were done. The cantilevers were tested under 4, 2 and 1 concentrated loads simulating traffic w ...
