Experimental study on bolted tensile joints applied to the cast iron deck module connection

Abstract

Recently the deterioration of RC slabs of the steel girder bridges has been increased. It is supposed that these updating is necessary in the future. The cast iron deck was developed as lightweight and highly fatigue resistant deck slab. The mechanical connections between these modules are inevitable because the cast iron deck is composed of multiple modules. On the other hand, shortening construction time is required for replacement RC slabs. We propose to use a high strength bolted tensile joint for the cast iron deck module connection. In this study, an experiment has been carried out for the specimens modeled as the cast iron deck module connection. It is confirmed that the mechanical behavior of this connection is clarified.
