Problems solved by technology

However, the existing experimental research and earthquake damage have proved that the plastic hinge area of ​​the frame structure is often difficult to repair after the earthquake, which will increase the time for the building structure to restore its function, and the repair cost of the structural plastic hinge area will also increase. Increase the indirect economic loss of the building structure after the earthquake
Therefore, the existing traditional frame design is not conducive to the rapid recovery of the frame structure after the earthquake.

Abstract

The invention relates to a novel controlled swing frame system with self-resetting energy-dissipating supports, which belongs to the field of anti-seismic structural systems. It is mainly composed of frame columns, frame beams, self-resetting energy-dissipating supports, controlled beam-column nodes, controlled column foot nodes and foundations. The main controlled frame structure is subjected to vertical loads. When the structural system is subjected to an earthquake, the self-resetting energy-dissipating supports dissipate the seismic energy and provide lateral stiffness and restoring force to protect the main controlled frame structure from damage.

Description

technical field [0001] The invention belongs to the field of anti-seismic structure systems, and in particular relates to a novel controlled frame structure system with self-reset energy dissipation supports. Background technique [0002] Frame structure is a commonly used lateral force-resistant structural system. The seismic design of traditional frame structures needs to realize "strong columns and weak beams" and "strong joints and weak members", so that the traditional frame structures can dissipate seismic energy through the plastic hinges formed at the beam ends and the bottom columns under the action of earthquakes, that is, through the The nonlinear response of the material in the plastic hinge area is used to dissipate energy, so as to achieve the seismic fortification goal of "no collapse in a big earthquake". However, the existing experimental research and earthquake damage phenomenon have proved that the plastic hinge area of ​​the frame structure is often diff...
