When there is a composite effect by concrete slab, in positive bending moment, it moves to a concrete slab side compared with the case where a composite effect does not have a neutral axis position. Consequently, when there is a composite effect, in positive bending moment, there are elastic rigidity, a rise of strength, and a restraint of horizontal buckling and upper flange
local buckling. On the other hand, as for the bottom flange of a steel frame, the big degree of stress compared with an upper flange. Furthermore, to the same growth ability steel material, it bends to the lower flange fracture of a composite girder, and growth ability becomes small compared with a pure steel frame beam.
