Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes
Structural Concrete, EarlyView.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 ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Structural Concrete, EarlyView.Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...

From section to structure: Assessing the impact of localized corrosion on reinforced concrete beams
Structural Concrete, EarlyView.Abstract The structural behavior of reinforced concrete (RC) elements affected by localized corrosion represents a major challenge for ensuring structural safety and for the proper design of strengthening interventions. The effects of localized corrosion on the flexural behavior of RC beams remain a topic of debate within the scientific community.

Structural Concrete, EarlyView.Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐
