Abstract

The invention relates to a shock absorption and isolation system and a bridge. The system comprise a bridge pier, a main beam arranged over the bridge pier; a first shock absorption and isolation mechanism connected between the bridge pier and the main beam and arranged in the transverse direction; and a second shock absorption and isolation mechanism connected between the main beam and the bridgepier and arranged in the longitudinal direction. The second shock absorption and isolation mechanism and the first shock absorption and isolation mechanism are arranged in an orthogonal mode. When anearthquake occurs in an external environment, the first shock absorption and isolation mechanism and the second shock absorption and isolation mechanism can work cooperatively at the same time; strong vibration generated by earthquakes is forcibly decomposed along respective movement directions; therefore, transverse and longitudinal motions are orthogonally separated to respectively reduce or eliminate the vibration in two different directions, the vibration damage of the earthquake to the bridge is greatly weakened, the shock absorption and shock resistance of the bridge are enhanced, and safe and reliable service of the bridge in an earthquake environment is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of shock absorption and isolation of buildings, in particular to a shock absorption and isolation system and a bridge. Background technique

[0002] In high-intensity areas, in order to improve the seismic performance of bridges, shock-absorbing and isolation systems with different structural forms and functions are widely used on bridges to ensure reliable and safe service of bridges. The shock absorption and isolation system generally includes viscous dampers, friction pendulums, etc. In the prior art, the viscous damper and the friction pendulum are usually used alone in the form of use, but their respective shock absorption and isolation capabilities have corresponding shortcomings, and the shock absorption and isolation effects are average. whole. Contents of the invention

[0003] Based on this, it is necessary to provide an anti-seismic isolation system and bridge, which aims to solve the problem ...
