Abstract

A seismic isolation bearing with non-linear dampers comprises a bearing body, wherein the bearing body includes an upper bearing plate (1), a middle lining board (2), a lower bearing plate (4), and a functional board (6) sandwiched between the middle lining board (2) and the lower bearing plate (4), and further comprises a seismic isolation device consisting of stopping blocks (5) and non-linear dampers (3). Several stopping blocks (5) are evenly fixed on the surface of the lower bearing plate (4) outside of the middle lining board (2) by energy dissipating bolts, and a plurality of non-linear dampers (3) are evenly set surrounding the outer periphery of the middle lining board (2) with one end thereof fixed to the middle lining board (2) and the other end fixed to the lower bearing plate (4).

Description

technical field [0001] The invention relates to the technical field of supporting devices for bridges and other construction projects, in particular to a non-linear damping radiation-reduction shock-isolation support. Background technique [0002] The support is one of the important components in bridges and construction projects. Its function is to transfer the upper load of the bridge and building structure to the pier through the support, and at the same time ensure the required force, displacement and rotation of the structure. [0003] In recent years, with the country's intensification of infrastructure construction, bridges and construction projects have developed rapidly, and various new structural types and functional bridges and buildings have emerged. At the same time, the technical performance, function and cost of the bearing put forward higher requirements. Especially after the 5.12 Wenchuan Earthquake, people became more aware of the seriousness of earthquake...
