[提要]  論述了碳纖維復(fù)合材料( CFRP)加固技術(shù)應(yīng)用于某大型公共建筑混凝土折梁加固的設(shè)計(jì)原理及施工過(guò)程，提出了用CFRP進(jìn)行梁正截面抗彎補(bǔ)強(qiáng)的簡(jiǎn)易計(jì)算方法。實(shí)踐證明該工程使用效果良好，顯示了碳纖維材料加固技術(shù)的良好前景。
[關(guān)鍵詞]  碳纖維復(fù)合材料 極限彎矩 破壞形狀 加固

This paper presented an example of CFRP applied to strengthen many special beams and described the full process for design and construction,especially presented an easy design method of how to calculate the ultimate capacity of the flexural beams. The result of reinforcement has been proved successful. It shows that the application of CFRP technique will have a good prospect.
Keywords:  Carbon Fiber Reinforced Plastic(CFRP); ultimate moment; failure mode; strengthening
