STUDY ON LOAD SHARING IN HIGH STRENGTH BOLT FRICTION-TENSION CONBINED JOINT OF CAST IRON DECK

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, the relationship between friction and tension type joint and the slip strength were quantitatively clarified using FE analysis.
