Flexural Behaviour of Geopolymer Concrete T-beams Reinforced with FRP or Hybrid FRP/Steel bars
… cause for concern for the construction industry. FRP bars are replaced for steel reinforcing bars in severe environments to prevent corrosion. Each tonne of OPCC produces an extra tonne of CO2. The OPCC must be replaced with binders that emit less CO2. Geopolymer binder is an alternative to …

Fatigue Life of Hybrid FRP Composite Beams
As fiber reinforced polymer (FRP) structures find application in highway bridge structures, methodologies for describing their long-term performance under service loading will be a necessity for designers. The designer of FRP bridge structures is faced with out-of-plane damage and delamination at …

Fracture analysis of debonding mechanism for FRP plates
Inevitable flaws in the concrete-FRP interface govern plate debonding, and are not amenable to finite element analysis because the models require far more detail than will ever be available for the interface. This thesis describes a global-energy-balance based fracture-mechanics model for the …

Slender FRP Elements as Discrete Reinforcement for Concrete
… focused on glass fiber reinforced polymer (GFRP) composites as the material for producing Needles. Although other materials can be used for producing Needles, GFRP materials were chosen for their unique mechanical properties, particularly, very high values of tensile strength and …

Energy Absorption of Metal-FRP Hybrid Square Tubes
… relative and absolute thicknesses of metal or FRP section has a substantial effect on energy absorption of the hybrid tubes. In particular, likelihood of delamination occurrence raises with increase in FRP thickness. This can reduce the energy absorption capability of the metal-FRP hybrid …
