Contributions to rebar-to-concrete interaction and its structural implications for design and monitoring applications

Enrique Corres Sojo

Bond between reinforcing bars and concrete has been the focus of extensive research over the last century. This is well-justified as the functioning of reinforced concrete intimately depends on the interaction between rebar and concrete, as for example cra ...

A New Panel Element Tester for the Investigation of Reinforced Concrete Behavior under Non-proportional Load Paths

Gilles Guignet, Elias Merhi, David Michael Volpe Ruggiero

The first Panel Element Tester was conceived by Vecchio and Collins at the University of Toronto in the late 1970s. This apparatus allows for the mechanical testing of concrete elements under combined in-plane normal and shear stresses and provided importa ...

Process development of pre-impregnated hybrid thin-ply composites

Alexios Argyropoulos

Thin-ply composites, obtained with recently developed fiber spreading techniques, rapidly gained industrial interest because they offer a large composite design freedom, and lead to a composite tensile strength that is close to that of the individual fiber ...

Microstructure of Crushable Expanded Clay Aggregates

Edward Carlo Giorgio Andò

The images show two different and complementary views of a mixture of Light Expanded Clay Aggregate (LECA) particles with size ranging between 0.25–1.0 mm. The upper-left is a SEM image showing a projected view of the particles, while the lower-left is a s ...

Review of fundamental assumptions of the Two-Phase model for aggregate interlocking in cracked concrete using numerical methods and experimental evidence

Aurelio Muttoni, Miguel Fernández Ruiz, Guillaume Anciaux, Max Tirassa, Mohit Pundir

Aggregate interlocking allows transferring shear and normal stresses through open cracks, and is considered to significantly contribute to the force transfer in cracked concrete. The complex phenomenon depends on the roughness of cracked surfaces, where ma ...

Progress in Self-Healing Fiber-Reinforced Polymer Composites

Véronique Michaud, Amaël Maximilien Cohades

This paper sets out to review the current state of the art in applying self-healing/self-repair to high-performing advanced fiber-reinforced polymer composite materials (FRPs). A significant proportion of self-healing studies have focused so far on develop ...

Study of the Propagation of Common Mode IEMI Signals Through Concrete Walls

Farhad Rachidi-Haeri, Marcos Rubinstein, Nicolas Mora Parra, Gaspard Lugrin

In this paper, a model to analyze the propagation of intentional electromagnetic interferences disturbances along penetrating conductors into concrete walls is proposed. The model is based on the transmission line theory and considers the attenuation of th ...

Healing of a glass fibre reinforced composite with a disulphide containing organic-inorganic epoxy matrix

Véronique Michaud, Amaël Maximilien Cohades

We report the development of an intrinsic healing glass fibre reinforced polymer (GFRP) composite based on a disulphide-containing organic-inorganic thermoset matrix. Thermomechanical experiments showed that the newly developed matrix has a combination of ...

Cement stress predictions after anatomic total shoulder arthroplasty are correlated with preoperative glenoid bone quality

Alexandre Terrier, Alain Farron, Raphaël Rodolphe Obrist

Hypothesis: We hypothesized that biomechanical parameters typically associated with glenoid implant failure after anatomic total shoulder arthroplasty (aTSA) would be correlated with preoperative glenoid bone quality. Methods: We developed an objective aut ...

Earthquake-induced loss assessment of steel frame buildings with special moment frames designed in highly seismic regions

Dimitrios Lignos, Seong-Hoon Hwang

This paper discusses an analytical study that quantifies the expected earthquake-induced losses in typical office steel frame buildings designed with perimeter special moment frames in highly seismic regions. It is shown that for seismic events associated ...

Stability of thin reinforced concrete walls under cyclic loads: State-of-the-art and new experimental findings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) walls may not achieve the expected ductile response but could possibly be triggered by out-of-plane displacements ...

Soft piezoresistive sensor model and characterization with varying design parameters

Jamie Paik, Amir Firouzeh

Recent robots target safety, reconfigurability and interactivity by addressing the “softness” of the hardware either by endowing additional degrees-of-freedom or through inherent compliancy. These robots require distributed sensing with flexibility and sof ...
