A Study on the Fabricated Concrete Deck Bridges

상판 조립식 교량 구조 개발에 관한 연구

The purpose of this study is to develop a new structural system for precast deck plate bridge. In order to investigate load distribution and composite effects by connecting diaphragms and precast deck plate to main girder with shear keys, computer analysis with F.E.M S/W package program ADINA was carried out. As results of analysis, the following could be concluded : -The distance between diaphragms with6m is suficient for crossing load distribution effects. -The composite effects by connection deck plate to main girder with shear key is reasonable. -The gap between deck plate and main girder under given load is negligible.
