Self-resetting steel frame eccentric support system

Abstract

The invention relates to a self-resetting steel frame eccentric support system and belongs to the field of structural engineering. According to the self-resetting steel frame eccentric support system,the major components of the welded part of a joint connecting device can be manufactured in factory, so that the construction cycle is greatly shortened, and the construction quality can be improved;an upper flange cover plate is set into an inwards covering plate mode for bumped amplitude control; a lower flange cover plate is set into an outwards covering plate mode to achieve high performance, good visibility and replacement decidability; a self-setting device can ensure a preset performance design objective for structural seismic energy dissipation and reduce post-seismic restoration costs, thereby ensuring structural safety; through targeted design, damage of a structure under seismic load are prone to taking place in dissipative components easy to replace such as high-strength bolts and connecting plates to facilitate post-seismic restoration. Therefore, the self-resetting steel frame eccentric support system is applicable to meeting the demands of development of fabricated steel structures with a restorable function.

Description

technical field [0001] This patent relates to a self-resetting steel frame eccentric support system, which belongs to the technical field of structural engineering. Background technique [0002] With the acceleration of the urbanization process, the development of the construction field and the continuous improvement of the technical level, coupled with the impact of environmental pollution and resource waste, the defects of poor environmental protection in the traditional building system are gradually exposed, and the green fabricated steel structure has begun to become a building The main types of systems. Compared with the traditional system, this system has significant advantages in terms of construction quality and construction efficiency. "Building blocks" is a representative construction method, which greatly speeds up the construction speed and saves project funds. Applying it to the design and development of various building systems is the main trend in the future...

[0003] The unreasonable design of the frame system causes brittle failure of the structure under the earthquake load, aggravates the earthquake disaster, and threatens the safety of people's lives and property

Existing studies have shown that reasonable design of joints can effectively improve the bearing capacity of joints, protect the main structure, realize express repair after the earthquake, and reduce economic losses; The time for concrete pouring on site; in addition, the traditional frame system is difficult to repair or the loss caused by irreparable damage is very huge. There is an urgent need for a recoverable functional structure that can be restored to use without repair or minor repair after the earthquake. It has also become a research hotspot in the field of international earthquake engineering in recent years.
