Static load test of RC T-beam bridge flexural strengthening with externally bonded steel plates

Externally bonding steel plates is a common method for strengthening old bridges. Structural features and diseases of T-beam bridge are described. The project Erdao River Bridge was taken as an example. Based on static load test, changes deflection stress studied at the bottom RC T-beams strengthened by externally in loading process. Numerical simulation also carried out. results test show that bearing capacity, bending stiffness deformation can be improved with plates. This paper provides good engineering practice experience reasonable application plate method.
