The invention relates to a multi-story high-rise assembled steel structure frame - prestressed centrally-braced system, belonging to the technical field of structure engineering. The multi-story high-rise assembled steel structure frame - prestressed centrally-braced system comprises assembled beams and slabs, assembled stand columns and prestressed sway braces. The assembled beams and slabs in the system consist of slabs, column base joints and open-web steel beams with section steel web members. The open-web steel beams are connected with the column base joints. The slabs are supported on the open-web steel beams. The assembled stand columns consist of box columns and flanges. During construction, the assembled beams and slabs and the assembled stand columns can be spliced to form a frame structure, and the prestressed sway braces are arranged on the basis of the steel frame, so as to improve the lateral rigidness of the structure. All members of the structure system are prefabricated in factories and are rapidly assembled through bolts on the construction site to form the structure system. Concrete pouring and welding operation are avoided, the defects of long construction period, serious material wastage, great pollution during construction and the like existing the traditional buildings are overcome, and the factory integrated production of buildings can be realized.

The invention provides an industrialized assembly type special-shaped column steel structure frame-eccentric support system and belongs to the technical field of structural engineering. The industrialized assembly type special-shaped column steel structure frame-eccentric support system comprises assembly type truss plates, assembly type columns and eccentric support members. Each assembly type truss plate comprises lattice truss beams and floor slabs and is prefabricated in a factory, and the assembly type truss plates and beam-column joints of the assembly type columns are spliced through beam-end seal plates in a construction site, and the assembly type columns are spliced among layers in the site through bolts to form a multiple-layer truss plate steel frame structure. Based on the truss plate steel frame structure, the eccentric support members serve as lateral force resisting members and are connected with the truss beams in the assembly type truss plates and the bottoms or the tops of the assembly type columns. The assembly type truss plates, the assembly type columns and the eccentric support members are prefabricated in the factory and are assembled in the construction site through bolts.

The invention discloses an industrialized assembling type special-shaped column steel structure-steel plate shear wall steel structure system and belongs to the technical field of structure engineering. The industrialized assembling type special-shaped column steel structure-steel plate shear wall steel structure system comprises an assembling type truss plate, assembling type columns and a steel plate shear wall. The assembling type truss plate comprises a lattice truss beam provided with a web member and a floor plate. The assembling type truss plate is prefabricated in a plant and spliced with beam column joints of the assembling type columns through a beam end sealing plate of the assembling type truss plate at the construction site, and the assembling type columns are spliced to form a multiplayer truss plate steel framework structure among layers through bolts at site. On the basis of the steel framework structure, the steel plate shear wall is connected onto the truss beam in a framework structure beam plate layer or the column bottoms or the tops to serves as a lateral load resistance element. The assembling type truss plate, the assembling type special-shaped columns and the steel wall plate shear wall member are all fabricated in the plant and assembled at the construction site through bolts.
