Introduction of the revised contents of composite steel concretebeams in China Design Code of Steel Structures (GB50017-2002)

This paper briefly introduces the revised contents of composite steel concrete beams in China Code for Design of Steel Structures (GB50017-2002), including the designing method and basic theory of negative bending regions in continuous beam, partial shear connection, composite beams with profiled sheeting, and the reduced stiffness method for calculating the deflection of the composite beam. The issues that need to be further done are also presented.
