Abstract
This paper proposed new type steel plate floor girder, as the bridge for rebuilding. This new type bridge is taking in for the steel plate floor of CT-shaped ribs and using section steel for all steel materials other than a deck plate. And this structure, the longitudinal joint of bridge was joined the adjoined angle steel web with the high-strength bolt in the deck plate lower part. This attained curtailment of manufacture cost and labor saving of local construction. And the static loading test was conducted about proposed steel plate floor girder, FEM nonlinear analysis was carried out simultaneously. Those results understand nonlinear characteristic of the structure of proposed steel plate floor girder and checked the structure performance as a highway bridge, and proposed the design technique of the high strength bolt connection.
