  • S031022 Proposed Allowable Depth of Local Corrosion in Bottom Plate of Oil Storage Tank to Prevent Low Cycle Fatigue

抄録

Procedure to calculate allowable depth of local corrosion in bottom plate of oil storage tank was proposed to prevent low cycle fatigue due to strong earthquake. The procedure was used to evaluate the possibility of low cycle fatigue failure for bottom plates in tanks in which deep corrosions were detected by continuous ultrasonic examination. In the case the depth of corrosion reaches to the half of original thickness of the plate, it was found that the possibility of low cycle fatigue failure should be considered depending on the configuration of local corrosion.
