Problems solved by technology

When the spherical bearing encounters earthquake or wind vibration, the bearing will extend the period of the structure through horizontal sliding, thereby reducing the acceleration response of the structure, but the horizontal sliding of the bearing will increase the displacement response of the structure to a certain extent , affecting the security of the structure

Abstract

The invention discloses an energy consumption spherical support base comprising a spherical support base body which can slide unidirectionally and a damping wall arranged on the spherical support base body. The spherical support base body comprises a lower support base plate, a middle main body arranged on the lower support base plate and an upper support base plate arranged on the middle main body. The bottom face of the damping wall is fixed to the top face of the lower support base plate. The upper end of the damping wall is fixedly connected with the middle main body. The energy consumption spherical support base has strong vertical bearing capacity, also has strong capacity of horizontal energy consumption and the excellent damping effect; unidirectional horizontal sliding of the spherical support base is achieved, meanwhile the certain rotating function, strong tensile capacity and insensitivity to the temperature are achieved, and reducing of structure responding can be achieved in a wide frequency domain range; and the damping wall of the energy consumption spherical support base is simple in structure, has the low requirement for sealing performance and is convenient to install and low in cost.

Description

technical field [0001] The invention relates to an energy-dissipating spherical bearing, which belongs to the technical field of civil engineering. Background technique [0002] In the field of civil engineering, spherical bearing is a widely used bearing form. In the prior art, the sliding vibration isolation technology is adopted for the spherical steel bearing. The horizontal sliding of the bearing is realized mainly through the combination of the flat stainless steel plate and the flat sliding plate, and the rotation of the ball bearing is realized through the combination of the spherical sliding plate and the middle spherical plate. When the spherical bearing encounters earthquake or wind vibration, the bearing will extend the period of the structure through horizontal sliding, thereby reducing the acceleration response of the structure, but the horizontal sliding of the bearing will increase the displacement response of the structure to a certain extent , affecting th...
