| 摘 要： | 通过计算内嵌碳纤维增强复含材料（CFRP）抗弯加固钢筋混凝土构件开裂时的开裂荷载和受拉钢筋屈服时的屈服荷载，并对加固梁和对比梁进行了静力加载试验，结果表明该计算结果和试验基本吻合，可以用来分析碳纤维板加固梁的效果。混凝土梁经碳纤维板加固后，开裂荷载和屈服荷载都有一定程度的提高，内嵌碳纤维板能提高梁的极限承载力，是一种有效的加固方法。

| Abstract: | By calculating the load of the concrete splitting and steel yielding on the beams with strengthened carbon fibre reinforced plastics （CFRP ） plate , static load tests are carried on between the strengthened beam and the normal beam .The results are in accordance with the theory and show the effect of the beams strengthened CFRP plate .The concrete splitting load and the ultimate bearing capacity of the beam strengthened are enhanced in a certain degree compared with the normal beam . Thus it is an effective method to use the CFRP plate to strengthen a beam . |
