Abstract

In welded steel structures, the fatigue failure sometimes occurs at the weld joints. The present maintenance is done by the watching of workpeople and the detection of the minute damage is very difficult. This study has investigated the way of detecting fatigue damages in some welded structural components. The examined structural components are beam-pillar joint test components and bead welding specimens. As a result, it has been confirmed that fatigue damages, which occur from the weld toe, can be detected with the monitoring of strain change near the weld toe.
