【摘要】 本文根据芳纶纤维加固钢筋混凝土梁和未加固的混凝土参考梁的抗弯性能静载试验研究,分析了芳纶纤维加固钢筋混凝土受弯构件的破坏过程,研究了加固后钢筋混凝土受弯构件正截面的破坏特征、受力特点及影响因素(粘贴层数和配筋率)。结果表明,粘贴芳纶纤维可以明显地增加钢筋混凝土梁的抗弯刚度,有效地提高钢筋混凝土梁的抗弯承载能力和构件的延性,为芳纶纤维应用于土木工程结构加固领域提供了理论依据。更多还原

【Abstract】 Based on the test of the flexural performance of reinforced concrete beams strengthened with aramid fiber reinforced plastics(AFRP)and reference beams,this paper analyzes the failure process and characteristics of the strengthened beams and factors that affect the failure of the strengthened beams.The test results illustrate that the bonded AFRP can effectively increase the flexural rigidity and enhance the flexural performance and durability of the members.更多还原
