［摘要］在完成2根預(yù)應(yīng)力碳纖維板加固混凝土梁試驗(yàn)研究的基礎(chǔ)上，提出了根據(jù)確定的目標(biāo)延性系數(shù)反算碳纖維板加固面積或初始張拉控制應(yīng)力的設(shè)計(jì)計(jì)算方法。通過計(jì)算結(jié)果與試驗(yàn)結(jié)果的比較，說明計(jì)算方法具有良好的適用性，可為實(shí)際工程設(shè)計(jì)提供參考。

Abstract:Based on the experiment of 2 reinforced concrete beams strengthened with prestressed CFRP plates, a design calculation is derived for determining the allowable plate area or initial tension control stress to achieve a target value of ductility. Calculational results are compared with experimental data,comparisons show that the calculation method have good applicability. It can provide a reference for engineering application of strengthening design.
Keywords:prestressed； carbon fiber reinforced plastics plates(CFRP plates)； concrete beams； ductility; test
