Abstract

The present study discussed fatigue performance on a column type transformer and pole top-type pillar subjected to wind load. For this purpose, a wind response observation, a finite element analysis, a fatigue experiment and estimation of cumulative fatigue damage were conducted. Furthermore, performance on a specimen whose fatigue performance was improved by changing space of an upper open area and smoothing weld toe was discussed. Consequently, cumulative fatigue damage of the well-performed pillar was about one-tenth of the original configuration.
