Regarding the rc beams subjected to concentrated load or even load and braced by bonding steel, an analysis is made on the relevant factors influencing maximum anchorage shear stress of steel sheet. the analysis is based on elastic theory and makes use of the formula for calculating anchorage shear stress of steel sheet. as indicated by the results, the maximum anchorage shear stress not only realtes to such parameters as height of cross section of rc beam and span but also relates to the thickness of adhesive layer, elastic modulus, thickness of steel sheet, and length of steel sheet. the present method will check maximum an chorage shear stress on the end of shear sheet so as to prevent rc beam from local damage. the present results will offer important reference for our country to further perfect bracing design by bonding steel method
