BRIDGING METHOD AND COMPOSITE GIRDER AND DECK THEREFOR

ARMSTRONG JOHN

Composite girder assemblies (10) are in use on a headstock (11) and piers (12) and comprises spaced webs (13) welded to top flanges (14) and bottom flanges (15). Cross bracing (16) is provided at the %, M½and % web length positions to restrain the bottom flanges from buckling sideways. Diaphragm assemblies (17) each interconnect the respective ends of the webs (13) and comprise a welded diaphragm plate (20), integral upper flange (21), integral lower flange (22) and bracing gussets (23). Full- height bracing webs (24) complete the diaphragm assembly (17). Club headed shear studs (25) are resistance welded to the top flanges (14) and upper flanges (21) and resist pull-out of a concrete deck (26). C*4D
