Problems solved by technology

Compared with the steel frame-reinforced concrete shear wall, the steel frame-steel plate shear wall has good ductility and energy dissipation capacity, which overcomes the cracking of the steel frame-reinforced concrete shear wall under the earthquake, which leads to the reduction of structural ductility Shortcomings
However, since the steel plate shear wall is prone to out-of-plane buckling, it is necessary to thicken the steel plate or use ribbed steel plate in the design, which increases its economic cost

Abstract

The invention provides a lateral force resisting system for a multi-story and high-rise steel structure and a bearing capacity calculating method. The lateral force resisting system comprises infill steel plates and is characterized in that the two sides of each infill steel plate are each provided with at least one external application carbon-glass hybrid fiber layer, and the infill steel plates are fixed to a steel frame. As the carbon-glass hybrid fibers are externally applied to the two sides of steel plates of a traditional steel frame-steel plate shear wall, the infill steel plates can be reinforced effectively, and the bearing capacity, ductility and energy consumption capacity of the structure are improved to form the novel lateral force resisting system for the multi-story and high-rise steel structure. The novel structure system can still meet the requirement for seismic resistance and energy consumption of the structure by the adoption of the thin steel plates, and the lateral force resisting system is good in economy and has broad market prospects.

Description

technical field [0001] The invention relates to the field of construction, in particular to a multi-layer, high-rise steel structure anti-lateral force system and a bearing capacity calculation method. Background technique [0002] Steel frame-steel plate shear wall is an excellent lateral force resistance system, which has been widely studied and applied in the United States, Europe and other western countries. At present, this structure is continuously used in high-intensity fortification earthquake areas in my country. Compared with the steel frame-reinforced concrete shear wall, the steel frame-steel plate shear wall has good ductility and energy dissipation capacity, which overcomes the cracking of the steel frame-reinforced concrete shear wall under the earthquake, which leads to the reduction of structural ductility Shortcomings. However, since the steel plate shear wall is prone to out-of-plane buckling, thicker steel plates or ribbed steel plates have to be used in...
