Anchorage of reinforcement in concrete corners: Experiments and refined measurements

Aurelio Muttoni, Enrique Corres Sojo, Xianlin Wang

The anchorage of reinforcement in concrete is a complex phenomenon typically governed by several failure modes, including: pull-out failure, splitting, side spalling, edge wedge spalling, and corner spalling, depending on multiple factors. Extensive resear ...

Local bond-slip model based on mechanical considerations

Aurelio Muttoni, Enrique Corres Sojo

Bond between reinforcing bars and concrete plays a crucial role in the behaviour of reinforced concrete structures, often characterized by the bond stress-slip relationship. Numerous relationships exist in the literature, incorporating various parameters a ...

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 ...

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 ...

Image-based techniques for initial and long-term characterization of crack kinematics in reinforced concrete structures

Aurelio Muttoni, Enrique Corres Sojo

In the recent years, Digital Image Correlation (DIC) was applied with very promising results to monitor cracks in reinforced concrete structures. However, current DIC measurements present some limitations to characterize the existing crack (already present ...

Bond of steel reinforcement based on detailed measurements: Results and interpretations

Aurelio Muttoni, Enrique Corres Sojo

Rebar-to-concrete bond is a fundamental aspect of the behavior of reinforced concrete structures. The characterization of the interface response is challenging due to the complexity of the physical phenomena and the large number of factors involved. Locall ...

Validation of bond models for the crack width estimation based on detailed measurements

Aurelio Muttoni, Enrique Corres Sojo

Crack formation and development in reinforced concrete structures is a complex mechanism affected by a large number of factors. Typically, the estimation of the crack width as a function of the reinforce-ment stress state is based on simplified assumptions ...

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 ...
