Abstract
Corrosion is major cause of deterioration of steel bridges, and corrosion damages seriously affect on the durability of steel bridges. So, corrosion damage must be carefully evaluated and the damaged part of members must be repaired or restrengthened. In many restrengthenning ways, reinforcement by cover plates is often selected because of its simplicity and effectiveness. But, in case of application to corroded members, there are some indefinite points. This report describes an investigation of reinforcement by cover plates that are connected with high-strength bolts and both use of high-strength bolts and adhesives.
