FATIGUE TESTS ON WELDED CONNECTIONS BETWEEN DECK PLATE AND TROUGH RIB IN STEEL PLATE DECK IN CONSIDERATION OF WELD PENETRATION

Abstract

Recently, some kinds of fatigue cracks have been discovered at the welded connection between trough rib and deck plate in the steel plate deck. In this study, finite element stress analyses, stress measurement tests and fatigue tests on model specimen for one panel of steel plate deck are performed in order to examine the cause of fatigue cracks originating at the welded joint between trough rib and plate deck and the influence of weld penetration depth and position of wheel load on stress properties.
