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.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

open access: yesStructural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

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

Innovative development and structural behavior of hollow columns using inflatable molds

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

open access: yesStructural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...
