Industrialized multi-story high-rise assembled steel structure frame - centrally-braced system

Abstract

The invention relates to an industrialized multi-story high-rise assembled steel structure frame - centrally-braced system, belonging to the technical field of structure engineering. The industrialized multi-story high-rise assembled steel structure frame - centrally-braced system comprises assembled truss plates, assembled flange columns and central bracing members. The assembled truss plates are prefabricated in a factory. On a construction site, the assembled truss plates are spliced together through beam end closing plates or column base joints to form frame structure beam-slab layers; the frame structure beam-slab layers are vertically connected through the assembled flange columns to form a multilayer steel frame structure; on the basis of the steel frame structure, the central bracing members are connected to truss beams or column bottoms in the frame structure beam-slab layers and are used as lateral-force-resistant members; and all members are prefabricated in the factory and are assembled through bolts on the construction site. In combination with modularization, factory production, standardization and assembling, the industrialized multi-story high-rise assembled steel structure frame - centrally-braced system has the advantages that the factory production and the on-site rapid assembling are realized; and on the premise that the construction quality is guaranteed, the construction speed is improved, the construction period is shortened and the construction cost is decreased.

Description

technical field [0001] The invention relates to an industrial multi-high-rise assembled steel structure frame-central support system, which belongs to the technical field of structural engineering. Background technique [0002] my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output for 16 consecutive years. Our country is less than 4%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of housing steel structures. [0003] At present, the systematic research on high-rise steel structure residences at home and abroad is in its infancy, and the inno...

Problems solved by technology

A lot of welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building.

[0004] In the traditional steel frame structure system, the lateral rigidity of the structure is difficult to meet the requirements, and the deformation is large, which is easy to cause damage to non-structural components. The industrialized multi-story fabricated steel structure frame-central support system adds lateral and longitudinal central support, which increases the lateral stiffness of the structure and improves the deformation performance of the structure
