Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin

open access: yesStructural 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.

Experimental study of the size effect on punching shear of steel fiber reinforced concrete slabs

open access: yesStructural Concrete, EarlyView.
Abstract As the behavior and design of steel fiber reinforced concrete slabs subjected to punching still remain an area of concern, the present work aims to provide a further contribution to the knowledge on punching behavior of slabs without transverse reinforcement.

Numerical analysis of the effects of corrosion on the punching shear capacity of reinforced concrete flat slabs with openings

open access: yesStructural Concrete, EarlyView.
Abstract The reinforcement corrosion is one of the main degradation mechanisms in reinforced concrete structures. Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete.

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

open access: yesStructural 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.
