Abstract: |
As a simple repair method for fatigue cracks in steel bridges, the resin injection method has been proposed. The method can decrease fatigue crack growth rate by injecting resin into a crack. In this study, the applicability of the method for cracks occurred by cyclic compressive loading was investigated by experiments and finite element analyses. The results revealed that the crack growth retardation can be expected even under the compressive loading when enough elastic modulus and infiltration of resin are achieved. |
