Prestressed assembly type steel frame friction damping structure system and design method thereof

Abstract

A prestressed assembly type steel frame friction damping structure system and a design method thereof comprise at least two layers of steel frame structures, wherein adjacent steel frame structures are disconnected at the joint of an upper-layer column and a lower-layer floor slab; the adjacent steel frame structures are connected in a sliding manner through a bidirectional sliding friction connecting device; the bidirectional sliding friction connecting device comprises an upper C-shaped plate, a lower C-shaped plate, a friction plate and a connecting piece; the plate surface of the upper C-shaped plate is provided with a first transverse strip hole; the plate surface of the lower C-shaped plate is provided with a first longitudinal strip hole; the upper C-shaped plate and the lower C-shaped plate are mutually inserted and connected with the connecting pieces in the corresponding first longitudinal strip holes through the first transverse strip holes; the upper C-shaped plate is connected with a bottom connecting plate; the lower C-shaped plate is connected with a top connecting plate; and friction plates are arranged between a first top plate and a second top plate, between a second top plate and a first bottom plate and between the first bottom plate and a second bottom plate. The prestressed assembly type steel frame friction damping structure system solves the technical problems of poor energy consumption performance and difficult construction of connecting joints of the traditional assembly type structural steel column connecting structure.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, in particular to a prestressed assembled steel frame friction damping structural system and a design method thereof. Background technique [0002] Prefabricated steel structure buildings refer to prefabricated buildings whose main structure is composed of steel components and assembled on site by prefabricated parts. The integration of interior decoration systems, as well as the process of planning, design, production and construction integration, and finally efficient and reliable assembly on the construction site, and the realization of a building that integrates building envelope, main structure, and electromechanical decoration, embodies the idea of ​​​​green buildings , is the development direction of modern architecture. In the traditional prefabricated structural system, the steel column connection structure is generally connected by welding or bolts; the connection nodes a...
