摘要
通过对碳纤维增强塑料筋(CFRP筋)混凝土梁和普通钢筋混凝土梁的试验,总结了CFRP筋混凝土梁的受力变形规律,在此基础上,讨论了CFRP筋混凝土梁有限元建模计算的方法和关键问题,并对不同配筋率的CFRP筋混凝土抗弯性能进行了计算研究。通过研究,给出了能够减少试验工作量的CFRP筋混凝土梁抗弯计算的原则和方法,而该方法又可进一步用于研究CFRP筋混凝土梁抗弯性能。
This paper summarizes deformation law of CFRP (Carbon fiber reinforced plastic) bar reinforced concrete beams by studying the CFRP bars reinforced concrete beams and ordinary reinforced concrete beams. Based on the study, this paper also discusses the Finite Element Modeling calculative methods and key problems of CFRP reinforced concrete beams,including calculating the bending resistance of CFRP reinforced concrete beams of varied reinforcement ratios. By study,the calculative principles and methods of CFRP bar reinforced concrete beams which can reduce experimental work are showed, and it can be used to further study the bending behaviors of CFRP reinforced concrete beams.
