Interface Shear Stress Analysis of Concrete Beam Strengthened with CFRP

Abstract:

Article Preview

Based on elastic theory, the four basic assumptions and the failure model of concrete beams strengthened with CFRP, deduced the formulae about the concrete beams strengthened with CFRP with concentrated load. Results show the biggest interface shear stress is at the at the anchor end, it not only relate to the material property of CFRP and concrete, but also to the thickness, width and bending moment at the anchor end etc.. Reducing CFRP stiffness and thickness or increasing viscose layer thickness, these can reduce the maximum interface shear stress at the end of anchoring.
