| Abstract: | Using REM and the comparing test methods, the relation between the overstress regions in concrete, which is near the tip of the notch and the interface between fiber laminate and concrete, and the bonding length for fiber laminate is sdudied. Based on the control index of the bonding outspread length which is brought forward in the current criterion, the expression of the reasonable bonding length for fiber laminate of the fiber-laminate-reinforced concrete beam with a V-notch under the 3-point bending conditions. |
