| Abstract: | An attempt is made to use fiber materials more fairly:to increase elongation and to decrease cost. An idea to strengthen reinforced concrete beams using hybrid?fiber?sheet is first proposed in the paper. The hybrid?fiber?sheet is come from the carbon fiber(CF) and glass fiber (GF) sheet. A contrast program on eight pieces of beams is conducted. Three types of strengthening materials: hybrid?fiber?sheet, CF sheet, and GF sheet are produced. A comparison is formed with the CF sheet to realize the performance of the hybrid?fiber?sheet. The results have shown that the hybrid?fiber?sheet has not only a higher ductility but also a lower cost. |
