Structural 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
Structural 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
Structural 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 ...

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin
Structural Concrete, EarlyView.Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods
Structural Concrete, EarlyView.Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders
Structural Concrete, EarlyView.Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

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 ...

Structural 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.
