玄武岩纤维布加固钢筋混凝土梁抗弯性能研究
Study on flexural behavior of reinforced concrete beams strengthened with basalt fiber sheets
摘要
Abstract
In order to study the influence of bonding BFRP material at the bottom of beams on the mechanical properties of RC beams,tests were carried out on four reinforced beams and one control beam,and the influence laws of the reinforcement layers,reinforcement width,and anchoring mode of basalt fiber cloth on the mechanical properties of RC beams were analyzed.The applicability of the formulas for calculating the bearing capacity of rein-forced beams proposed by GB 50367-2013 and ACI 440.2R-17 was verified by the test results.The results show that the use of basalt fiber cloth to strengthen RC beams can greatly increase the yield load and ultimate load of RC beams,and the maximum increase can reach 33.14%and 25.00%respectively.The more layers of basalt fiber cloth reinforcement,the greater the stiffness of the beam.Under the same reinforcement quantity condition,the smaller the reinforcement width,the greater the stiffness improvement.The reinforcement reduces the beam ductility,the maximum reduction is 34.96%.The average error of GB 50367-2013 and ACI 440.2R-17 ultimate bearing capacity calculation results is 4.00%and 6.00%respectively,which can give ideal calculation results and can be used for the calculation of ultimate bearing capacity of BFRP strengthened RC beams.关键词
