摘要
对 4根普通钢筋混凝土梁和 3根预应力混凝土梁进行了加固后的弯曲试验研究。试验结果表明 ,碳素纤维布可明显提高梁的正截面抗弯承载力。提出的加固后混凝土梁的正截面抗弯承载力计算公式 ,计算值与试验值吻合较好。
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.
