Abstract

The invention relates to an intelligent friction pendulum shock insulation support, which comprises an upper seat plate, a spherical pendulum, a lower seat plate and an elastic body, wherein the top end of the upper seat plate is used for being connected with a main bridge and bearing the main bridge; the top end of the spherical pendulum is slidably connected with the upper seat plate, and the bottom end can swing on the lower seat plate; the elastic body is connected to the bottom end of the lower seat plate and used for being connected to a pier; a strain sensor is arranged on the elastic body and is used for measuring the strain of the elastic body; an angular velocity measuring instrument is arranged on the spherical pendulum and used for measuring the rotation angular velocity of thespherical pendulum; a displacement measuring device is arranged on the upper seat plate or the spherical pendulum and used for measuring the horizontal displacement D of the upper seat plate or the spherical pendulum; a controller is connected with the strain sensor, the angular velocity measuring instrument and the displacement measuring device, and is used for calculating to obtain a vertical load W borne by the shock insulation support according to the strain of the elastic body; and the horizontal stress F of the support is calculated based on a preset calculation formula according to W and D, and real-time monitoring of the working performance of the friction pendulum shock insulation support is achieved.

Description

technical field [0001] The application relates to the field of bridge supports, in particular to an intelligent friction pendulum shock-isolation support. Background technique [0002] With the development of economy and the increase of traffic volume, the damage and destruction of bridge bearings have become one of the main diseases of bridges in active service in our country. At present, seismic isolation bearings are widely used in the field of bridges, and the friction pendulum isolation bearings in seismic isolation bearings have been used in actual bridges in many countries around the world due to their remarkable isolation effect, large load bearing, and relatively mature technology. It has been widely used in engineering. Friction pendulum isolation bearings are the main force-transmitting components directly between the upper structure and the lower structure of the bridge structure. Their damage and destruction will accelerate the attenuation of the life of the br...
