Abstract: A new design and rapid construction method for flush assembly of prefabricated steel beams and floor slabs is disclosed. The upper flange of prefabricated steel beams is “” shaped, which consists of horizontal flange, vertical flange and top flange. Both beam stiffeners and studs are set on the horizontal flange, in which the former can strengthen the bearing capacity of the beam and avoid its local deformation, and the latter can fix the floor slab; prefabricated studs and precast concrete inside the vertical flange in the factory are used to constrain the deformation of upper flange. There is no limitation with respect to the form of floor slab, which is connected with the prefabricated steel beam by hitching the prefabricated rebar ring of the floor slab to the welded studs of the upper flange of the prefabricated steel beam.
