摘要

Research was performed to investigate the performance of transverse panel-to-panel connections for full-depth concrete bridge deck panels on continuous steel girder bridges. Two nonprestressed and four posttensioned connections were designed and tested in cyclic loading. Each connection was tested on a full-scale two-girder specimen in negative bending with a simulated HS-20 vehicle loading. The nonprestressed connections and the two posttensioned connections with 170 psi (1.2 MPa) of initial stress exhibited cracking and leaked water by the end of the tests. The two posttensioned connections with 340 psi (2.3 MPa) initial precompression performed well, with no leaking and no full-depth cracking. It is recommended that panel-to-panel connections be designed so that the net tension, which is the applied tensile stress minus the initial precompression, at service load moment be less than 3 ,f'_c~(1/2), with f'_c being the smaller of the deck concrete and connection grout compres-sive strength.
