| 摘 要： | FRP布具有轻质、高强、耐腐蚀、施工方便等优点,在土木工程中得到广泛的应用,尤其是用于旧有结构的加固。在加固中,结构往往处于二次受力状态,导致FRP布相对于结构应变滞后。本文对目前FRP布加固混凝土梁滞后应变的研究进行综述,并通过实际算例,比较各算法的优缺点。

| Abstract: | Fiber reinforce polymer (FRP) is a high-performance material,with many goog performance,such as low weight,high strength,well corrosion resistance and convenience in construction.FRP sheet is widely used in the Civil Engineering,especially in the strengthened structure.In the strengthened structure,FRP sheet strain is lager than old concrete because of secondary load.The researches of strain lag were reviewed in this paper and make a comparison of every calculation by calculation case. |
