EXPERIMENTAL ANALYSIS OF REINFORCED CONCRETE SLABS STRENGTHENED WITH STEEL PLATES

Abstract

The present research is concerned with the strengthening of reinforced concrete slabs with epoxy – bonded steel plates. The strengthening is intended to enhance the inherent resistance of existing slabs. The strengthened slabs have been analyzed through the experimental program done. The parameters studied in the present study are the thickness, dimensions, and location of steel plates. The more effective parameter which enhances the overall behavior of R.C. slabs is the effect of steel plate dimensions more than the thickness effect The max increases in ultimate strength are found in slabs S3 and S5 as (135%) and (79.6%), respectively. From the analysis results, using steel plates for strengthening of R.C. slabs can enhance the overall resistance of these members significantly.
