| Research Abstract |
In order to develop the unified design method for strengthening by external bonding and overlaying, the followings are presented: Prediction models for various debonding types at interface between substrate concrete and reinforcing materials, Influences of fatigue, moisture, freeze thaw cycles and interface roughness on interface bond strengths, Optimum reinforcing material properties and reinforcing methods (dimension and location), Experimental evidence of enhancement of ultimate member strength by overlaying under traffic loads, and (5) Applicability of 3D numerical analysis to simulate member strength after strengthening. After compiling all the results, latest guidelines for strengthening of concrete structures as well as strength prediction models after strengthening are presented.
