Open-hole square steel pipe truss profiled steel plate shear wall and its construction method

Abstract

The invention discloses a hole opening square steel pipe truss profiled steel plate shear wall and a construction method. The shear wall comprises two profiled steel plates, wherein square steel pipetrusses are arranged between the two profiled steel plates and comprise chord members and web members. The profiled steel plates comprise a plurality of wave crest positions. Holes are formed in the square steel pipe trusses and correspond to the wave crest positions of the profiled steel plates. The shear wall is arranged between a frame beam and a frame column. A gap is reserved between the shear wall and the frame column. For a non-ductile reinforced concrete frame structure, the hole opening square steel pipe truss profiled steel plate shear wall is a novel reinforcement method, is a novelstructural member which is developed on the basis of a profiled steel plate shear wall and a flat steel plate combined shear wall, and has the advantages of being small in cross section size, large in side rigidity resistance, high in anti-seismic property and the like.

Description

technical field [0001] The invention relates to a square steel pipe truss with open holes and a profiled steel plate shear wall to reinforce a non-ductile reinforced concrete frame and a construction method thereof, belonging to the field of construction technology. Background technique [0002] One of the main structural forms of existing buildings in our country is reinforced concrete structure. A considerable part of it has the phenomenon of large axial compression ratio, low volume hoop ratio, and insufficient ductility and energy dissipation capacity. This structure is called "non-ductile reinforced concrete structure". Framework". Non-ductile reinforced concrete frame refers to a reinforced concrete frame structure with poor ductility that only considers the vertical load and wind load of the structure itself in the design process, but does not consider the requirements of seismic design. Studies have shown that due to poor ductility and energy dissipation capabilitie...

Problems solved by technology

[0004] The purpose of the present invention is to provide a non-ductile reinforced concrete frame reinforcement method to solve the welding defects caused by the welding connection of traditional truss-type profiled steel plates. Due to the small overall rigidity of the large bay, the problem that supports need to be provided, improve the non-ductile reinforced concrete frame structure. strength and energy dissipation
