THEORETICAL SOLUTION OF BOND SPLITTING STRENGTH OF RC USING PARABOLIC MODEL OF BOND CONSTITUTION
This study presents the theoretical solution of bond stress distribution along the reinforcement in concrete structure solving fundamental differential equation on bond problem with modeled bond stress slippage relationship by parabolic curve. The modeled relationship has almost the same shape with previously proposed by the authors considering the equilibrium conditions of bond stress and splitting stress of concrete. By the theoretical bond stress solution, the bond strength is solved by the integration of the bond stress distribution. The previously proposed calculation method using the equivalent bond stress block (EBSB) is verified by the theoretical solution, and the calculated values of bond strength show a good agreement with theoretical ones. The relationship between bond strength and bond fracture energy can be also led by the theoretical solution.
