Problems solved by technology

[0004] The hysteresis curve of the plate rubber bearing is narrow and long, the energy dissipation capacity is poor, and the rubber is aging; the small amplitude earthquake excitation of the low frequency characteristics of the lead rubber bearing may amplify the seismic response of the lead bearing system. The shock absorption and isolation effect of the bridge is poor; the high-damping rubber bearing has the problem of rubber aging; the friction pendulum bearing will cause a certain amount of upward displacement of the upper structure, causing uneven driving and secondary internal forces of the main beam, thus affecting the upper structure. cause harm

Abstract

The invention discloses a steel damping horizontal seismic mitigation and isolation bearing, which comprises a bearing body. The bearing body comprises an upper base component, a rotary structure, a middle base plate component and a lower base component, wherein a limited baffle ring is arranged on one surface of the upper base component; steel dampers are uniformly distributed and fixed on one surface of the lower base component along an annular direction; the rotary structure and the middle base plate component are matched between the upper base component and the lower base component; the rotary structure and the limited baffle ring are in clearance fit; a sliding plate is also arranged between the middle base plate component and the lower base component; middle hinge points of the steel dampers are connected with the middle base plate component. According to the steel damping horizontal seismic mitigation and isolation bearing provided by the invention, the upper base component, the lower base component, the steel dampers, the rotary structure and the middle base plate component are adopted to form the steel damping horizontal seismic mitigation and isolation bearing, so that the steel damping horizontal seismic mitigation and isolation bearing not only has all functions of a general support, but also has the characteristics of double functions of friction damping and steel damping under a certain seismic force working condition.
