This book provides an explicit description of the interface fracture behavior of FRP bonded concrete that is subjected to temperature and moisture effects. Extensive characterization of each constituent material is performed. Measured properties, in conjunction with peel and shear fracture load data, are used to calculate joint toughness by means of a newly developed tri-layer fracture model. Computed toughness, along with outputs of a fracture mode-mix analysis and a 3D moisture diffusion simulation are synergistically analyzed. Results suggest that moisture can physically change...
