Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes

Structural Concrete, Volume 27, Issue 5, Page 7048-7065, October 2026.
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...

Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

Structural Concrete, Volume 27, Issue 5, Page 7667-7679, October 2026.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, Volume 27, Issue 2, Page 1364-1382, April 2026.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, Volume 27, Issue 1, Page 193-210, February 2026.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while
