| Abstract: | Based on the strip method,a relay numerical calculation method for the bending bearing capacity of reinforced concrete beams strengthened with externally bonded FRP sheets considering the effect of the second loading was proposed.Comparing the calculation results with the existing test results,it was verified that the numerical calculation method is accurate enough to be used to calculate the bending bearing capacity of strengthened reinforced concrete beams.To consider the effect of the second loading on t... |
