In this paper three specimens were tested to study the mechanical behaviors,including failure- modes,load-carrying capacities and deflections of composite steel-concrete beams with re-entrant trough profiled steel sheeting.

A simplified method is presented for calculating the partial shear connection strength of a composite slab with profiled steel sheeting subjected to loads of various patterns.

Introducing four structural types of major girders of urban pedestrian overcrossing, computing principle of steel and concrete composite girder, classification and shape selection of composite girder, study and application of molded steel sheet and concrete composite girder.

To analyze the composite effect of Steel-precast concrete beams under static loads,three tests of steel-precast concrete composite beams under static concentrate lateral loads were performed.
