Problems solved by technology

However, due to the uncertainty and complexity of the seismic action, the structure may suffer from an earthquake with a greater intensity than the fortification, which will seriously damage the structural components.
In addition, although the structure may not collapse after being subjected to an earthquake with fortification intensity, some components cannot be repaired due to excessive residual deformation. In the end, the entire structure can only be demolished and rebuilt, which has caused huge waste and affected people's normal life.

Abstract

The invention discloses a frame structure with a self resetting function. The frame structure comprises two I-shaped columns, a T-shaped upper rod, a T-shaped lower rod and at least one energy-consuming connection piece. The two I-shaped columns are vertically placed on a concrete foundation; each stiffened rib plate is connected with the concrete foundation through a prestressed bar; the T-shaped upper rod is hinged to the two I-shaped columns through upper lug plates of upper end plates of the two ends of the T-shaped upper rod; the T-shaped lower rod is hinged to the two I-shaped columns through lower lug plates of lower end plates of the two ends of the T-shaped lower rod; the T-shaped upper rod and the T-shaped lower rod are arranged in up-down parallel in a spaced mode; and an upper web of the T-shaped upper rod and a lower web of the T-shaped lower rod are connected through the at least one energy-consuming connection piece. Compared with a traditional steel frame, the frame structure has the self resetting function.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a frame structure with a self-resetting function. Background technique [0002] The anti-seismic thinking in my country at the present stage is "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes". This anti-seismic idea requires that the main structure should not be damaged and can be repaired after the structure encounters an earthquake with fortification intensity. However, due to the uncertainty and complexity of the seismic action, the structure may suffer from an earthquake with a greater intensity than the fortification, which will seriously damage the structural components. In addition, although the structure may not collapse after being subjected to an earthquake of fortification intensity, some components cannot be repaired due to excessive residual deformation. In the end, the entire str...
