Assembly-type multi-storey steel special-shaped column framework-steel plate shear wall structure system

Abstract

The invention discloses an assembly-type multi-storey steel special-shaped column framework-steel plate shear wall structure system, and relates to the technical field of structural engineering. The assembly-type multi-storey steel special-shaped column framework-steel plate shear wall structure system comprises an assembly-type truss plate, assembly-type special-shaped columns and a steel plate shear wall component. The assembly-type truss plate comprises a lattice truss girder provided with a steel channel web member, and a floor slab. The assembly-type truss plate is prefabricated in a plant. On a construction site, the assembly-type truss plate is spliced with a flange plate of the assembly-type special-shaped columns through a beam-end blanking plate of the assembly-type truss plate. The assembly-type special-shaped columns are spliced on site through bolts between storeys to form a multi-storey truss plate steel framework structure. One the basis of the steel framework structure, a steel plate shear wall is connected to the truss girder in a beam and slab layer of the steel framework structure or the bottom or the top of each column and used as a lateral load resistance component. The assembly-type truss plate, the assembly-type special-shaped columns and the steel plate shear wall component are all prefabricated in the plant and assembled through bolts on the construction site.

Description

technical field [0001] The invention relates to an assembled multi-high-rise steel special-shaped column frame-steel plate shear wall structure 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 steel structures for houses (including residences). [0003] At present, the systematic research on high-rise steel structure residences at hom...

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 fabricated multi-story steel special-shaped column frame-steel plate shear wall structure system is based on the steel frame. The steel plate shear wall is added to increase the lateral stiffness of the structure and improve the deformation performance of the structure
