Abstract:The transverse joint of prefabricated bridge girder usually adopts the wet joint form of rebar cross lapped deck slab. But the calculation method of this connection mode needs to be improved, and there is no test data basis for its normal service performance. Therefore, the performance of wet joint of bridge deck under the different joint widths, reinforcement forms and joint material combinations is revealed through the axial tension test, which provides the test data for theoretical calculation methods and the reference for design.
