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 capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

Structural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.
