Multi-story high-rise assembled steel structure frame - prestressed eccentrically-braced system

Abstract

The invention relates to a multi-story high-rise assembled steel structure frame - prestressed eccentrically-braced system, belonging to the technical field of structure engineering. The multi-story high-rise assembled steel structure frame - prestressed eccentrically-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 eccentric sway braces are arranged on the basis of the steel frame to form energy-dissipating beam sections, so as to improve the lateral rigidness and the energy dissipation capacity 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.

Description

technical field [0001] The invention relates to a multi-high-rise assembled steel structure frame-prestressed eccentric support system, which belongs to the technical field of structural engineering. Background technique [0002] According to the statistics of the China Iron and Steel Association, my country's steel output exceeded 700 million tons in 2011, ranking first in the world's steel output for 16 consecutive years. The development of the structure is seriously lagging behind. At present, in developed countries, such as the United States and European countries, the steel structure construction area accounts for more than 50% of the total construction area, and Japan accounts for 80%, while our country accounts for less than 4%. [0003] Moreover, traditional buildings have disadvantages such as long construction period, serious waste of materials, and heavy pollution during construction, which cannot meet the needs of rapid reconstruction after the earthquake. There...
