Description

TECHNICAL FIELD

[0001] The present application relates to the field of civil engineering anti-seismic reinforcement, and in particular to a pin shaft connected deformation compensation and energy dissipation force transmission device and an installation method thereof. BACKGROUND

[0002] In recent years, earthquake disasters have occurred frequently around the world, causing serious threats to people's lives and property. Under the action of earthquakes, the stability and seismic resistance of buildings directly affect people's life and property safety, and it is crucial to control inter-story displacement. Excessive inter-story deformation may lead to the destruction or even collapse of building structures. Therefore, controlling inter-story displacement helps to improve the seismic performance of buildings and protect people's lives. At present, the inter-story displacement of structures is basically controlled by setting shear walls, increasing reinforced concrete columns, and using seismic bracing systems, which can effectively reduce inter-story deformation, thereby reducing the risk of stress concentration of structures and improving the overall seismic capacity of buildings. The traditional concept of seismic resistance indeed focuses on protecting people's lives during earthquakes, which is crucial. However, with the development of society and the acceleration of urbanization, people's demand for the rapid recovery of structural functions after earthquakes is also increasing.

[0003] By reinforcing the frame with a cable bracing system, the lateral stiffness of the structure can be improved, and the inter-story displacement of the structure can be limited. However, under the action of a larger earthquake, the inter-story displacement of the structure increases, and the cable bracing may reach its control stress or even the ultimate stress due to the increase in deformation, which poses a safety hazard and may even break, thereby affecting the seismic performance and safety of the structure. Secondly, there are no energy dissipation components in the cable bracing, and the insufficient energy dissipation capacity may cause severe damage to the main load-bearing components of the structure, thereby leading to premature failure. Therefore, it is necessary to further improve the deformation space and energy dissipation capacity of the cable bracing, which is beneficial to reduce the dynamic response of the structure and the bracing, thereby improving the seismic performance of the structure and reducing the repair and maintenance costs of the structure.
