Abstract

This paper presents comprehensive test data on the effect of Epoxy-Bonded Steel Plates on the ultimate strengths, ductilities, failure modes and structural deformations of flexural members strengthened with steel plates on the tension face. To achieve the purpose, six specimens with and without Epoxy-Bonded steel Plates were tested. The results show that Epoxy-Bonded Steel Plate is very effective for strengthening the damaged structure, That is, plated members have enhanced ultimate strength at all load levels until failure. However, the failure mode of plated members is brittle as soon as steel plate separates from concrete face.
