Abstract
The Mode I fracture behaviors of FRP sheet-concrete interfaces are studied by means of conventional three-point bending tests of artificially notched composite beams. Different adhesives and different bonding substrates (concrete and mortar) are used. Based on the test results, the interfacial Mode I fracture energy is evaluated parametrically. And also, the interfacial tension-softening diagram has been derived through Niwa’s improved J-integral method and verified through FEM analysis.
