Abstract Since the nineteenth century, reinforced concrete was evolved as a crucial material for construction. This popular composite is broadly used in different building typologies. However, decaying of steel rebar due to corrosion identified hindrance that can affect quality structures. In reference this, glass fiber-reinforced polymer (GFRP) bar essential because corrosion-resistant propert...

Plantation softwood timber poles are associated with low natural durability, and it is also not clear what the effects of high humidity environment on long-term performance composite action integrity such a system. This paper presents durability study for proposed using (GFRP) glass fiber-reinforced polymer as confinement system wooden sourced from plantation timber. Radiata pine 6 m length wer...

A theoretical study of Glass Fiber Reinforced Polymer (GFRP) beams subjected to biaxial bending moments is presented with a focus on the influence higher-order effects maximum normal stresses. It shown that type loading causes dramatic increase in stress for GFRP beam when induced torsional are included. The demonstrates traditional first-order theory can grossly underestimate beam. Based numer...

The rule of mixtures (ROM) method is often used to estimate the tensile strength of fiber reinforced polymers (FRPs) reinforcing bars (rebars). Generally, the ROM method predicts the FRP rebars’ modulus of elasticity adequately but overestimates their tensile strength. This may result from defects occurred during manufacture that prevent the used materials from exhibiting a sound performance an...

This paper presents a numerical study of the structural behaviour of concrete bridge deck slabs under static patch loads and dynamic traffic loads and an investigation of compressive membrane action (CMA) inside slabs. Those deck slabs were reinforced with Glass Fibre Reinforced Polymer (GFRP) bars. Non-linear finite element analysis (NLFEA) models were established using ABAQUS 6.10 software pa...

Failures in FRP-strengthened reinforced concrete (RC) members may occur by flexural failures of critical sections or by debonding of FRP plate from the RC beams. Debonding in the FRP/adhesive/concrete interface region may cause a significant decrease in member capacity leading to a premature failure of the system. There is a need for improved knowledge of the debonding processes under mechanica...
