High-rise fabricated steel structure prestressing eccentrically braced system of holding-on splicing

The invention relates to a high-rise fabricated steel structure prestressing eccentrically braced system of holding-on splicing. The structure system is formed by assembling fabricated floor slabs, fabricated braces and fabricated flange columns by adopting bolts; the fabricated floor slabs can be spliced into a required size, and are spliced by adopting the bolts to form the whole floor slab of a building; corrugated web steel channel beams are adopted as the fabricated floor slabs; webs of two corrugated steel channel beams at the joint of the adjacent fabricated floor slabs are butted in a holding-on manner; assembly connection is performed on the webs through the bolts; the assembled steel beams are in a holding-on state, and therefore, the shear capacity of each assembled steel beam is effectively improved. Industrialized production and rapid on-site assembly are realized by the steel structure system disclosed by the invention, and meanwhile, the on-site assembly of the steel structure system disclosed by the invention is performed completely by adopting the high-strength bolts, and therefore, environmental pollution caused by concrete pouring and steel welding is avoided.
