Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

open access: yesStructural 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.

On the preservation of reinforced concrete architectural masterpieces: The challenges of the REcube project

open access: yesStructural Concrete, EarlyView.
Abstract The preservation of reinforced concrete masterpieces from the 20th century poses a complex challenge. These structures often combine architectural, historical, and technological value, which standard engineering codes and conservation practices are not fully equipped to address. The Erasmus+ REcube project responded to this gap by promoting an

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

open access: yesStructural 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 ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.

Mechanics‐based model for cold joints in reinforced concrete members

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.
