Shear transfer model for ultra‐high‐performance concrete incorporating fiber bridging mechanism

Structural Concrete, Volume 26, Issue 5, Page 5999-6018, October 2025.
Abstract Ultra‐high‐performance concrete (UHPC) exhibits exceptional mechanical properties, including high shear strength, partly attributed to the fiber bridging mechanism. However, existing shear transfer models for normal‐strength concrete have not considered the significant contribution of fibers.

Cyclic bending behavior of pre‐cracked thin‐walled elements in high performance fiber reinforced concrete

Structural Concrete, Volume 26, Issue 5, Page 6057-6073, October 2025.
Abstract High‐performance fiber reinforced concrete (HPFRC) is increasingly being adopted for thin elements, such as façade panels, due to its outstanding mechanical properties and attractive finishes. These elements endure cyclic loads during their service life, impacting material properties and potentially leading to fatigue failures, particularly in

A shear failure analysis of ultra‐high‐performance concrete based on modified contact density and concrete damaged plasticity models

Structural Concrete, Volume 26, Issue 4, Page 5249-5265, August 2025.
Abstract Ultra‐high‐performance concrete (UHPC) becomes a promising composite material in structural concrete due to its exceptional mechanical and durability properties. However, the performance and damage characteristics of UHPC under different loading scenarios remain a subject of ongoing research.

UHPFRC Application in the Isabey-Darnley Pedestrian Bridge

Second International Interactive Symposium on UHPC, 2019
1.Project overview The Isabey-Darnley pedestrian bridge is located in Montreal (Quebec, Canada) over Highway 520 close to the International Airport. This new structure replaces the former reinforced concrete pedestrian bridge that was built in 1967, which suffered of early concrete spalling and rebar corrosion after only 40

Limit analysis and design recommendations for fiber‐reinforced concrete subjected to shear

Structural Concrete, Volume 26, Issue 1, Page 293-318, February 2025.
Abstract It is widely recognized in both research and practice that fibers have great potential to partially, or completely, substitute conventional transverse reinforcement in webs of girders subjected to moderate shear forces. However, despite extensive research in recent years, there is still no consensus in the research community on the ...

Experimental characterization of a cost‐competitive tailor‐made HPFRC mix design for wide application in precast girder of roadway bridges

Structural Concrete, Volume 25, Issue 2, Page 935-955, April 2024.
Abstract This paper presents a comprehensive study on the development of a cost‐effective, high‐performance fiber reinforced concrete (HPFRC) for the construction of a 60 m‐span U‐girder roadway bridge without stirrups in the webs, meeting the design requirements of fck ≥ 100 MPa and the post‐cracking flexural strength fR3k ≈ 8–10 MPa.

Rocket blast resistance of the fully demountable high performance FRC tongue and groove blocks

Structural Concrete, Volume 25, Issue 2, Page 826-849, April 2024.
Abstract Within the scope of this study, the design and testing of a fully demountable high‐performance fiber‐reinforced concrete (FRC) barriers with high resistance to sudden dynamic explosion and impact loadings is investigated. In order to solve such an engineering problem, a special FRC “tongue and groove” blocks are designed in a way that could be
