The Research on Bearing Carrying Capacity of Aging Reinforced Concrete Beam Strengthened with CFRP
Through the bending capacity test on the aging reinforced concrete beam before and after being strengthened with CFRP, the load-deflection curve and the bending capacity of the beam were obtained. The test showed that the capacity and stiffness of the beam with CFRP increased in various degrees, the post-strain of CFRP caused by secondary load would affect the high tensile strength of CFRP, and the bending capacity of the beam with CFRP decreased due to the change of material mechanical properties of the corroded reinforced concrete beam. Based on the material mechanics properties of aging reinforced concrete beam, the numerical simulation technology of the whole curve process of aging reinforced concrete beam strengthened with CFRP was established. The calculation results coincide well with the results of test, which provides reference for the calculation of strengthening design of aging reinforced concrete beam.
