An enhanced analytical model for predicting shear strength in reinforced concrete beams with corroded reinforcement

Structural Concrete, EarlyView.
Abstract This paper presents an analytical model to predict the shear strength of RC beams affected by corrosion within the Level IIb framework of fib Model Code 2020. Corrosion is accounted for by (i) reducing the area of longitudinal reinforcement, (ii) degrading the yield strength of stirrups according to Imperatore's law, and (iii) reducing the ...

Experimental investigation on post‐installed anchorages with cast‐in anchor reinforcement under tension loading

Structural Concrete, EarlyView.
Abstract Anchors are used to connect different structural and non‐structural components to reinforced concrete structures. Anchorages when subjected to tension loading might fail in different failure modes, with concrete cone breakout (CCB) being one of the most common.

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
