Abstract

In recent years, the fatigue damage of sign pillars on highway bridges used rubber bearings becomes a problem. So we, the authors conformed the reinforcing effect of the UV-Curable-FRP-Sheet Reinforcement for pillars by vibration tests. And them to confirm the effect of the fatigue strength improvement by this reinforcing method, we verified the reduction of the crack progress speed on a flat panel model with FEM. As a result, this reinforcing method was proved able to reduce the crack progress speed of this model by half.
