Journal ArticleDOI
Assessment of the structural performance of corrosion-affected RC members based on experimental study and probabilistic modeling
TL;DR: In this paper, the effects of the spatial variability in the steel corrosion on the structural behaviors of five corroded reinforced concrete (RC) beams were investigated and a finite element (FE) method was used to evaluate the structural performance of RC members subjected to reinforcement corrosion.
Journal ArticleDOI
Reliability estimation of corroded RC structures based on spatial variability using experimental evidence, probabilistic analysis and finite element method
TL;DR: In this article, the effects of main parameters (i.e., current density, concrete cover, rebar diameter, and fly ash) on the spatial variability associated with steel weight loss, corrosion crack, and structural behavior of accelerated-corrosion RC beams using X-ray radiography and digital image processing were investigated.
Journal ArticleDOI
Effects of concrete flow on the distribution and orientation of fibers and flexural behavior of steel fiber-reinforced self-compacting concrete beams
TL;DR: In this article, a finite element analysis was performed to evaluate the structural performance of SCFRC and SFRC beams considering the varying fiber distribution properties observed in the X-ray images.
Journal ArticleDOI
Experimental investigation of the spatial variability of the steel weight loss and corrosion cracking of reinforced concrete members: novel X-ray and digital image processing techniques
TL;DR: In this article, X-ray photography is applied to observe steel corrosion in reinforced concrete (RC) beams, and the steel weight loss is estimated by the digital image processing of the Xray photograms.
Journal ArticleDOI
Effect of the correlation of steel corrosion in the transverse direction between tensile rebars on the structural performance of RC beams
TL;DR: In this article, the effects of localized corrosion and the correlation of steel corrosion between tensile rebars on the structural performance of corroded RC beams were investigated through experiments and finite element (FE) analyses.
