Abstract
Friction pendulum bearings have universal properties satisfying various demands when supporting buildings, bridges, and industrial facilities. The oscillation period of the bearing, vertical carrying capacity, damping, displacement ability, and ability to receive tensile load can be chosen independently. Dynamic oscillation periods from 1 to 5 s, shifts of up to 1.5 m, high carrying capacity and damping can be provided. Bearings can endure vertical loads of up to 13 500 tons and have minimal construction costs. Data are given on the influence of earthquakes and other force effects on the thermal state and characteristics of frictional pendulum bearings used as seismic isolators on petroleum and gas platforms of the “Sakhalin-2” project.
