Abstract

The invention discloses a multi-dimensional energy dissipation and seismic mitigation type cold-formed thin-walled steel structure residential system. The seismic mitigation type cold-formed thin-walled steel structure residential system comprises a bottom guide rail, a top guide rail, a horizontal cross brace, a wall column, an energy dissipation diagonal brace middle part, an energy dissipationdiagonal brace yield section, an energy dissipation diagonal brace end part, a rigid diagonal brace, a self-tapping screw, a friction gasket, a covering plate, a truss upper chord, a truss lower chord, a truss column, a truss diagonal brace, a chemical bolt spring, a mass steel plate, a corrugated steel plate, a reinforcing mesh and a lightweight concrete plate. A corrugated plate-lightweight concrete-chemical bolt spring-bolt spring-mass steel plate jointly forms a tuned mass energy dissipation device, and the energy dissipation and seismic mitigation capacity of the cold-formed thin-walled steel structure residential system floor system is effectively improved. The industrialized and integrated modes of the structural system are outstanding, the construction speed is high, the advantagesof light weight, high strength and energy dissipation and seismic mitigation are integrated, and the application prospect is very wide.

Description

Technical field [0001] The invention relates to a multi-dimensional energy-consuming and shock-absorbing cold-formed thin-wall steel structure residential system, belonging to the field of assembly-type light steel structure shock-absorbing control and construction technology, in particular to the cold-formed thin-wall steel structure residential system through various shock absorption The device reduces the structure's response to dynamics under wind loads and earthquakes, achieving the effect of multi-dimensional vibration reduction and energy consumption. Background technique [0002] The main components used in the cold-formed thin-walled steel structure residential system are derived from cold-rolled hot-dip galvanized steel sheets, which are finished steels with various cross-sectional shapes formed by steel plates or strips in cold conditions. They are highly efficient cross-section steels. The shape is C-shaped or U-shaped. The cold-formed thin-walled steel structure res...

AI Technical Summary

Problems solved by technology

Due to the gradual increase in the construction of cold-formed thin-walled steel structure residences, it is also widely promoted to multi-rise residences, but its lack of earthquake resistance will reduce its reliability when building high-rise residences, especially in strong earthquake areas. For low-rise structures, it cannot meet the requirements. If the cold-formed thin-walled steel structure residential system is used in areas with high seismic intensity fortification, it needs to use shock absorption technology to improve its energy consumption capacity. Therefore, the cold-formed thin-walled steel structure residential system is reducing Research on earthquake control is urgently needed
