摘要
本文采用有限元方法对CFRP加固一次和二次受力钢筋混凝土梁的抗弯性能进行了分析,探讨了CFRP加固钢筋混凝土梁在短期荷栽作用下裂缝的发展规律以及裂缝发展的影响因素,并与试验结果进行了比较。结果表明,有限元分析数据模型与CFRP加固钢筋混凝土梁的抗弯性能非常比较接近,CFRP加固钢筋混凝土梁大幅度提高了其抗疲劳性能,所以,碳纤维布加固钢筋混凝土梁将要广泛的应用到实际的工程领域。
Using the finite element method of CFRP reinforcement are analyzed first and two times by the flexural performance of reinforced concrete beam force, discusses the influence factors of CFRP strengthened reinforced concrete beam under the action of plant development regularity of cracks and crack development in short-term load, and compared with test results were. The results show that, the finite element analysis of data model and CFRP consolidation of the flexural behavior of reinforced concrete beam is very close to. Research results show that, CFRP reinforced concrete beams strengthened greatly improve the fatigue performance of reinforced concrete beams, therefore, will be widely used in practical engineering fields of carbon fiber reinforced.
