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 ...

Model uncertainties in action effects and load bearing capacity calculation in statically indeterminate reinforced concrete structures

Aurelio Muttoni, Alain Nussbaumer, Xhemsi Malja

For the dimensioning and assessment of structures, it is common practice to compare action effects with sectional resistances. Extensive studies have been performed to quantify the model uncertainty on the resistance side. However, for statically indetermi ...

Experimental investigation of dowel action in reinforcing bars using refined measurements

Aurelio Muttoni, Marko Pejatovic

In typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either expli ...

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 ...

Verification of shear failures of cantilever bridge deck slabs subjected to concentrated loads

Aurelio Muttoni, Miguel Fernández Ruiz

Shear design and verification of bridge deck slabs subjected to concentrated loads (as those of wheels from traffic) is a topic subjected to scientific and engineering debate, where several questions remain open. Several design procedures have been propose ...

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 ...

Steel stresses and shear forces in reinforcing bars due to dowel action

Aurelio Muttoni, Marko Pejatovic

Reinforcing bars in structural concrete are typically designed to carry axial forces. Nevertheless, due to their bending stiffness, the bars can also carry transverse forces, that are associated with the localized bending mechanism (dowel action) resulting ...

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 ...

Fibre orientation in SFRC slabs and consequences for punching shear and flexural resistance

Aurelio Muttoni

The use of steel fibre reinforced concrete (SFRC) is a well-known method for enhancing the punching and flexural resistances of flat slabs. The structural performance of SFRC elements depends significantly on the fibre distribution and orientation, which a ...

Stress Fields and Strut-and-Tie Models as a Basic Tool for Design and Verification in Second Generation of Eurocode 2

Aurelio Muttoni, Miguel Fernández Ruiz

Within the frame of the revision of the Eurocode 2 for concrete structures, the section devoted to strut-and-tie design has been up-dated to enhance its applicability, its consistency with other sections and its ease-of-use. As a result, a number of change ...
