Large-span swing self-resetting structure

Abstract

The invention discloses a large-span swing self-resetting structure. The large-span swing self-resetting structure comprises a concrete foundation, a plurality of bearing columns, a truss roof, a column foot joint structure and a beam end joint structure, wherein the bearing columns and the concrete foundation are vertically arranged, and the truss roof is horizontally arranged at the top ends of the bearing columns; the concrete foundation is provided with limiting grooves for installing the bearing columns, and the positions between the limiting grooves and the bearing columns are filled with column foot flexible cushion layers used for wrapping the bottom ends of the bearing columns; the column foot joint structure comprises column foot cantilever plates, anchor rods and column foot disc spring sets; the column foot cantilever plates are connected to the side wall faces, close to the bottoms, of the bearing columns; a plurality of anchor rods penetrate the column foot cantilever plates to be fixedly connected with the concrete foundation; and the column foot disc spring sets are connected to the anchor rods on the sides, away from the concrete foundation, of the column foot cantilever plates in a sleeving manner. Thus, swing can be conducted during strong earthquakes, forming of plastic hinges at column foot joints is avoided, the structural stability is high, the self-resetting capability is high, the structural damage is small under the strong earthquakes, and the structural residual strain is small after the earthquakes.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures, in particular to a large-span swing self-resetting structure. Background technique [0002] Early earthquake-resistant engineering research mainly focused on reducing the collapse of buildings and casualties under large earthquakes, that is, "there is no collapse after a large earthquake." However, multiple earthquake damages have shown that the economic losses caused by the loss of normal functions of buildings under the action of earthquakes have become more and more prominent , that is, the cost of equipment such as building interior decoration, non-structural components and indoor important devices often exceeds the structural cost of the building. [0003] In order to improve the seismic performance of building structures and ensure the safety of people's lives and property, recoverable functional structures that can quickly restore the normal function of the structure after ...

AI Technical Summary

Problems solved by technology

[0005] As the fastest-growing building structure in the past few decades, large-span spatial structures are somewhat insufficient in seismic research, and with the needs of economic development, many major projects need to be constructed on sites with high seismic intensity or seismic stability , if the earthquake effect is not fully considered in engineering, it will cause major safety hazards
