| Abstract: | In this study, an economical strengthening method is suggested which can drastically heighten ultimate moment of reinforced concrete beam strengthened with GFRP and steel plate in both compression zone and tension zone .The strengthening design steps and relate fomula are presented. Five beams selected by practical strengthening engineering are tested in construction site .From the analysis of experiment result we can know that the strenthening is very ideal. |
