Description

Technical Field

[0001] The utility model belongs to the technical field of seismic isolation and vibration reduction, and particularly relates to a tensile resistance device. Background Art

[0002] To resist the damage of seismic forces to buildings, a seismic isolation layer composed of friction pendulum bearings or isolation rubber bearings and other seismic isolation and vibration reduction devices is arranged below the building or between floors to extend the natural vibration period of the entire structural system and reduce the horizontal seismic action input to the superstructure. In addition, when the building structure is subjected to horizontal wind loads, a vertical uplift force will also be generated on the seismic isolation and vibration reduction structure. The friction pendulum bearing or isolation rubber bearing in the seismic isolation layer plays the role of bearing vertical loads and horizontal energy dissipation, but the building seismic isolation friction pendulum bearing or isolation rubber bearing cannot bear the uplift force due to the influence of the main body structure and can only be used in combination with other tensile resistance devices. At present, some tensile resistance devices have appeared on the market, but they are only limited to being used in cooperation with rubber bearings, and there is no good solution to the elevation generated when the existing structure works in cooperation with the friction pendulum.
