The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

Creep investigation of GFRP RC Beams - Part A : Literature review and experimental Study

Journal of Materials and Engineering Structures, 2014
GFRP composite bars are excellent alternative to steel bars for reinforcing concrete structures in severe environments. However, studies on creep phenomenon of GFRP reinforced concrete structures are limited.

Rural but not radical right: The rural‐urban cleavage in Norway

Scandinavian Political Studies, EarlyView.
Abstract Conventional wisdom claims that rural voters are politically mobilized by right‐wing and culturally conservative forces, while urban voters are left‐leaning and have progressive cultural views. Leveraging original survey data from Norway, our work challenges this dichotomy.

Continental‐wide prioritization of protected areas to address global and habitat‐specific goals for avian biodiversity conservation

Conservation Biology, EarlyView.
Abstract The United Nations and European Union have set ambitious conservation goals to halt and reverse declines in biodiversity by protecting 30% of land and sea areas by 2030. Effective conservation planning requires evidence‐based spatial prioritization to maximize the coverage of species within designated protected areas.

Quantifying Fiber Bridging in Mode I Fatigue Delamination of CFRP/GFRP Hybrid Laminates Using a Superposed Traction–Separation Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Hybrid CFRP/GFRP laminates offer an attractive balance between mechanical performance, damage tolerance, and cost efficiency. However, fiber bridging during mode I delamination increases crack‐growth resistance while masking the intrinsic fatigue behavior of the material. This study applies a traction–separation‐based superposition approach to
