Rehabilitation of Strength of Steel Plate with a Corroding Hole Bonded by Composite Patches
The failure mode of steel plate with a center elliptic corroding hole double-sided adhesively bonded by carbon fiber composite patch is identified and studied, and analytical solution to load-carrying capacity of damaged steel plate bonded by composite patch is presented in this paper.Ultimate load of patched steel plate corresponding to each failure mode is derived and calculated respectively, the load carrying capacity of the patched plate is equal to the minimum value of these calculations.Yielding load when yielding occurs near the hole-edge of repaired structure from present method was compared to the results ofANSYS FEA, and the ultimate load of repaired plate from present method was compared to the test results.Results indicate: Repaired by bonded composite patch, static strength and loading carrying capacity of damaged steel plate or structures can be effectively restored.Yielding load and ultimate load of patched steel plate is visibly increased.The present analytical results have a good agreement with FEA and experimental results.
