【Abstract】 As an exploration of strengthening reinforced-concrete beam(RC-Beam),this paper combined the advantages of the methods of strengthening reinforced concrete beam with external prestress in gluing steel plate.Not only were the consolidate effect and mechanism of strengthening RC-Beam with external prestress in gluing steel plate discussed in this paper,but also strength,rigidity and advanced stress site of crack of RC-Beam were studied,which will be significant for strengthening RC-Beam.更多还原
