Experimental Study on the Composite Bridge Deck of Hollow Section

In this paper, flexural test, girder-connection test and barrier-connection test for the pultruded composite bridge deck of hollow section, were carried out and its structural characteristics were evaluated. In the flexural test specimen, deflection was measured at center of the span and strains were measured at various locations to see the structural behavior up to the failure. In addition, finite element analysis was performed for the flexural test specimen and the results were compared with experiments, and load carrying capacity was evaluated. Also, field load test was conducted for the demonstration plate girder bridge and other field applications were described.
