The Arousa Island bridge. Complete refurbishment and 10 years analysis description

Structural Concrete, Volume 25, Issue 3, Page 1554-1570, June 2024.
Abstract The Isla de Arousa Bridge, 1980 m long, is the only road access to Isla de Arousa. Built in 1985, this single‐cell box girder divided into 40 spans runs entirely over the sea. In response to corrosion damage, the local government decided to make an intervention with an ambitious repair project in 2009.

A Study of the Shear Behavior of Concrete Beams with Synthetic Fibers Reinforced with Glass and Basalt Fiber-Reinforced Polymer Bars

Buildings
The use of synthetic materials with high corrosion resistance in a concrete matrix yields structures that are more durable and suitable for use in aggressive environments, eliminating the need for frequent maintenance.

Structural evaluation of RC overhang cantilever slab strengthened with FRP near‐surface mounted (NSM) composites for bridge applications

Structural Concrete, Volume 25, Issue 2, Page 1105-1128, April 2024.
Abstract This paper presents the findings of a large‐scale experimental study that focus on assessing structural behavior of reinforced concrete (RC) cantilever slabs with carbon/epoxy fiber‐reinforced polymer (CFRP) composite strips using a near‐surface‐mounted (NSM) approach.

Fibre composites for high pressure pipeline repairs, in-air and subsea: an overview [PDF]

, 2012
In 2001 it was reported that in North America alone, corrosion to the Oil & Gas pipeline distribution network cost approximately $2-3.3 billion per annum with 10% of that cost being associated with actual failure of the pipeline.

Neural network‐based models versus empirical models for the prediction of axial load‐carrying capacities of FRP‐reinforced circular concrete columns

Structural Concrete, Volume 25, Issue 2, Page 1148-1164, April 2024.
Abstract This study presents new neural‐network (NN)‐based models to predict the axial load‐carrying capacities of fiber‐reinforced polymer (FRP) bar reinforced‐concrete (RC) circular columns. A database of FRP‐reinforced concrete (RC) circular columns having outside diameter and height ranged between 160–305 and 640–2500 mm, respectively was ...

Study on bending failure and crack characteristics in ductile fiber‐reinforced concrete beams

Structural Concrete, Volume 25, Issue 2, Page 916-934, April 2024.
Abstract In this study, we designed six polypropylene fiber‐reinforced concrete (PP‐FRC) beams and three reinforced concrete (RC) beams for experimental studies. Then, we analyzed the effects of incorporating PP fibers on the cracking performance of PP‐FRC beams from the perspectives of load‐displacement response, crack distribution, crack depth, crack

Finite element modeling of steel bar buckling in FRP-confined RC columns [PDF]

, 2015
Fiber-reinforced polymer (FRP) confining jackets offer an attractive solution for the seismic retrofit of reinforced concrete (RC) columns. For an accurate prediction of the strength and ductility of FRP-confined RC columns, it is necessary to understand

Experimental Investigation of Ductility in GFRP RC Beams by Confining the Compression Zone

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Nowadays, building structures in corrosive environments requires some considerations. Being lightweight, high tensile strength, and corrosion resistance are the features that make fiber‐reinforced plastic (FRP) bars an alternative component for longitudinal steel reinforcement of concrete.
