Assembling type swing self-resetting steel support structure system

Abstract

The invention discloses an assembling type swing self-resetting steel support structure system. The system comprises structural columns and structural beams, which form a main structure, wherein the main structure and a steel support are connected through energy consumption elements; self-resetting stay ropes are arranged along steel columns of the steel support, the upper ends of the self-resetting stay ropes are tensioned at the tops of the steel columns of the steel support, and the lower ends of the self-resetting stay ropes are poured into a cast-in-situ foundation; and the steel support consists of slender steel components and is connected with the cast-in-situ foundation through a swing node. According to the assembling type swing self-resetting steel support structure system, the steel support serves as a whole to swing during the earthquake and does not generate relative deformation with the main structure, the energy consumption elements are deformed, and the energy is dissipated; after the earthquake, the structure is restored to an original state through the self-resetting stay ropes, so that the use functions of the structure is guaranteed; and the basic components are slender, and splicing parts are connected by virtue of bolts and can be produced in factories and spliced on site, so that the site project duration can be shortened. The assembling type swing self-resetting steel support structure system has the advantages of strong building adaptability and shock resistance, simplicity in construction, high construction quality, short project duration and the like.

Description

technical field [0001] The invention belongs to the field of anti-seismic structure systems of civil engineering, and in particular relates to an assembled swing self-resetting steel support structure system. Background technique [0002] Earthquake is a sudden and extremely destructive natural disaster, which poses a serious threat to human society. my country is one of the areas in the world where earthquake disasters occur frequently. Actively responding to these earthquake disasters is an important task for building an urban and rural earthquake prevention and disaster reduction system. In the field of civil engineering, the anti-seismic concept to deal with earthquake disasters has experienced the development from the "seismic resistance" of increasing the cross-section, to the "shock absorption" of additional dissipative energy and the "seismic isolation" of isolating ground vibrations. In recent years, it has moved towards Development in the direction of "recoverable...

Problems solved by technology

With the advancement of industrialization research, the self-resetting concept has also been introduced into prefabricated shear walls, such as the prefabricated self-resetting shear wall structure (CN 204876196 U), etc., which mainly rely on the deformation between the upper and lower walls. The energy dissipation and self-resetting functions are formed by using the spring and the damper, but the wall is not fully swayed, and the shock absorption form of the swing wall is not formed.
