Small, EarlyView.Viologen derivatives are employed to tackle BPNS oxidation challenges through a noncovalent strategy. Comprehensive characterization techniques, complemented by DFT calculations, provide detailed insights into these interactions. Notably, XPS analysis reveals that MV‐BPNS hybrids experience minimal oxidation under ambient conditions, highlighting the ...

Structural Concrete, EarlyView.Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Structural Concrete, EarlyView.Abstract With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...

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
