CFRP加固RC连续梁负弯矩区试验研究
Experimental Study on Strengthening Negative Moment Areas of RC Continuous Beams with CFRP
摘要
Abstract
Flexural loading tests were carried out on three RC continuous beams strengthened with CFRP at negative moment areas. The influence of CFRP amount on flexural load carrying capacity was investigated. The experimental results showed that the flexural load carrying capacity and flexural rigidity of midspan were increased effectively by the strengthening. The availability factor of CFRP decreases with the increase of the layer. The calculated results have good agreement with the experimental ones.关键词
