[提要] 對(duì)4根普通鋼筋混凝土梁和3根預(yù)應(yīng)力混凝土梁進(jìn)行了加固后的彎曲試驗(yàn)研究。試驗(yàn)結(jié)果表明,碳素纖維布可明顯提高梁的正截面抗彎承載力。提出的加固后混凝土梁的正截面抗彎承載力計(jì)算公式,計(jì)算值與試驗(yàn)值吻合較好。
[關(guān)鍵詞] 碳素纖維布 混凝土 梁 加固 受彎承載力Concrete structure strengthened with carbon fiber reinforced plastic sheet( CFS) is a new retrofit method in the field of civil engineering. Three reinforced concrete beams and four prestressed concrete beams have been tested on bending strength. The experimental results show that the CFS can improve the bending strength of the beam obviously. The calculation formula of bending strength proposed shows good agreement with experimental data.
Keywords: carbon fiber reinforced plastic sheet; concrete; beam; strengthening; bending strength
