Abstract Fiber reinforced polymer (FRP) rebars have increasing popularity in the construction industry all around world although steel are widely used for reinforcing of concrete so far. FRP bars, which higher tensile strength compared to with same nominal diameter under normal conditions, composed resin matrix and fibers. In this paper, load-bearing capacity after elevated temperature expositi...

The purpose of this study was to propose a new numerical modeling of the glass fiber cloth reinforced denture base resin (GFRP). The proposed model is constructed with an isotropic shell, beam and orthotropic shell elements representing the outmost resin, interlaminar resin and glass fiber cloth, respectively. The proposed model was applied to the failure progress analysis under three-point ben...

A far-field airborne radar (FAR) nondestructive testing (NDT) technique integrating inverse synthetic aperture radar (ISAR) measurements and a backprojection algorithm for the condition assessment of glass fiber reinforced polymer (GFRP)–wrapped concrete structures is proposed. The method is directed toward the detection of near-surface defects and delaminations located in the vicinity of GFRP–...

Bond-slip behaviour of glass fiber-reinforced polymer (GFRP) bars embedded in conventional concrete has been widely investigated. In contrast, the bond-slip near-surface mounted (NSM) GFRP bonded reinforced recycled aggregate (RAC) seems to be less explored, while materials have increasingly used due reasons environmental pollution and resource exhaustion. This study aimed experimentally theore...

The axial compressive strength of unidirectional FRP made by pultrusion is generally quite lower than its axial tensile strength. This fact decreases the advantages of FRP as main load bearing member in engineering structure. A theoretical iterative calculation approach was suggested to predict the ultimate axial compressive stress of the combined structure and analyze the influences of geometr...
