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 ...

The transfer of forces through rough surface contact in concrete

Max Tirassa

Aggregate interlocking is a phenomenon occurring when the opposite sides of a concrete crack slide relative to each other. Due to surface roughness, protruding material from one crack-side can engage with the opposite one and thus exchange forces. This aff ...

Influence of cracking and rough surface properties on the transfer of forces in cracked concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Max Tirassa

Aggregate interlocking is acknowledged as one of the most significant actions transferring shear forces in cracked concrete structures and has been investigated for several decades. Despite the many experimental programmes and previous efforts to develop m ...

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 ...

Modern experimental research techniques for a consistent understanding of aggregate interlocking

Aurelio Muttoni, Miguel Fernández Ruiz, Max Tirassa

Aggregate interlocking is considered as one of the most important shear transfer actions in cracked concrete members without shear reinforcement. This research project analyses the fundamentals of aggregate interlocking by means of a specific experimental ...

Interface Stresses in Cracked Concrete: Testing for Review of Its Fundamentals, High Tech Concrete: Where Technology and Engineering Meet

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

Aggregate interlock is one of the most significant stress transfer actions in cracked concrete and its understanding is fundamental in order to predict the strength of many concrete structures, particularly members failing in shear. Several test programmes ...
