Description :

Composite means that the steel structure of a bridge is fixed to the concrete structure of the deck so that the steel and concrete act together thus reducing deflections and increasing strength this is done using shear connectors fixed to the steel beams and then embedded in the concrete. Other types of composite construction are mentioned including the timber concrete slab bridge a timber steel composite truss utilizing high strength bridge strand as the lower chord a wood steel open web joist which provides naiable chords and light gage metal decking with a concrete slab. Composite structures of steel and concrete beams slabs columns and frames for buildings 3rd edition rp johnson. Composite steel concrete beams are the earliest form of the composite construction method in the us a patent by an american engineer was developed for the shear connectors at the top flange of a universal steel section to prevent longitudinal slip this was the beginning of the development of fully composite systems in steel and concrete. Composite structures of steel and concrete have become popular for a number of reasons one reason is that while concrete is excellent for dealing with compressive forces steel also can carry large tensile stresses in some sense any reinforced
