With regard to the RC beams strengthened by bonding steel sheet against the action of concentrated and evenly distributed load, an analysis is made on the factors influencing maximal normal stress against peeling of steel sheet. The analysis is based on theory of elasticity and takes advantage of the formula for computing normal stress against peeling of steel sheet.By adopting the method of present work, the maximal normal stress against peeling at the ends of steel sheet can be checked, the occurrence of local peeling destruction of the RC beams can be prevented. The results of the present work will provide important references for further perfecting strengthening design of bonding sleel sheet method in our country.
