ELEMENT TENSILE LOADING EXPERIMENT ON HIGH－STRENGTH BOLTED FRICTION－TENSILE JOINTS OF CAST IRON DECK PANELS

Abstract

The cast iron deck is a lightweight deck slab with excellent fatigue resistance. There is a problem that the deck is separated when negative bending acts on the joint. As a countermeasure, we proposed a structure that uses both friction joint by the splice plate to the upper surface of the deck and tension type joint of end ribs. In this study, we confirmed the behavior of this joint structure up to the final stage and clarified the limit state by the elemental experiment.
