摘　　要：提出高强玻璃纤维 (SGF)布和碳纤维 (CF)布层间混杂加固混凝土梁、柱的思路并进行试验研究。结果表明 ,相对CF布加固方法 ,SGF CF混杂纤维复合材料 (HFRP)加固法既能在保证承载力的前提下显著提高构件的延性 ,又能显著降低加固成本 ,仅刚度略有下降。A method to strengthen concrete beams and columns by using laminated hybrid high strength glass fiber sheets and carbon fiber sheets was proposed,and an experimental study was performed.It is shown that,compared with the CF sheet strengthening members,under the premise of assuring load carrying capacity,the hybrid fibre sheet strengthening concrete members have not only a higher ductility but also a low cost;only the stiffness of the strengthened members decreases slightly.
