Full swing structural system containing swing columns and swing walls and construction method of full swing structural system

Abstract

The invention provides a full swing structural system containing swing columns and swing walls and a construction method of the full swing structural system. The full swing structural system is mainlycomposed of a swing wall part, a frame part and energy dissipation components. The swing walls are hinged to a foundation, and anti-buckling supports are arranged at the two ends of the wall bottoms.The frame part is composed of the elastically recoverable swing columns and frame beams, and the upper ends and the lower ends of the swing columns are connected with the frame beams through recoverable column feet. The swing walls are connected with frames through energy dissipation dampers. Under the action of a horizontal earthquake, the structural system transmits lateral stiffness and interlayer shear force through the swing walls, so that the structural deformation is uniform. The seismic energy is dissipated through the energy dissipation dampers arranged at the side edges of the swingwalls and the anti-buckling supports at the bottoms of the swing walls. The elastic deformation of the swing columns ensures that a frame body does not have yield failures. After the earthquake, thestructural system can be repaired by replacing the anti-buckling supports at the bottoms of the swing walls and the energy dissipation dampers at the side edges of the swing walls.

Description

technical field [0001] The invention relates to the technical field of civil engineering structures, in particular to a full swing structure system including a swing column and a swing wall. Background technique [0002] In the early swaying building structures, the constraints between the superstructure and the foundation were mainly relaxed, allowing the superstructure and the bottom of the foundation to rise to a certain extent. In this way, the wall swayed and the ductility requirements of the superstructure under strong earthquakes were reduced. , reducing earthquake damage. [0003] The reinforcement project of the G3 teaching building of Tokyo Institute of Technology is a relatively successful case of a swing structure, but the deformation between the frame structure and the swing wall is not coordinated. Although there are energy-dissipating connectors on both sides of the wall, when the deformation is large, the beam-column joints of the frame part are prone to pla...

Although there are energy-dissipating connectors on both sides of the wall, when the deformation is large, the beam-column joints of the frame part are prone to plastic failure

[0004] At this stage, some scholars have also studied a column-end hinged controlled swing frame, whose lateral stiffness is mainly provided by the X-shaped steel plate buckling damper between the columns, and self-resetting is realized through the prestressed tendons in the columns, but it may Insufficient lateral rigidity, inconvenient construction, insufficient wind resistance and small earthquake resistance, etc.
