Seismic steel ball bearings in the late 1980s from the development in the United States, and is mainly used for house building structure. The nature of seismic steel ball bearing friction damping also supports, but it relies on two friction bearing surfaces to achieve normal function. Lower bearing plate bearing is a large concave spherical surface, the center portion of the seat when the earthquake seismic steel ball bearing. Along the lower bearing plate concave spherical swing displacement occurs, the use of a simple pendulum mechanism to extend the natural cycle of the lower part of the structure to reduce the damping force of the earthquake Pedestal wholesale, while during an earthquake, the ball swinging panel along When the lower seat swing, ball panel elevation changes, the superstructure is raised, acting through the potential to achieve the purpose of seismic energy consumption. Ball bearing swing panel after the earthquake, will be automatically reset by the weight of the upper structure. Holder can be slid in any direction, whose maximum size is primarily controlled by the design displacement. Seismic steel ball bearings have the following characteristics: seismic steel ball bearings as seismic bearing, must have the carrying capacity, resilience functions; seismic steel ball bearings hysteresis characteristics (load - deformation curves) full of wind-induced vibration and large, medium and small earthquakes can play a seismic effect; seismic steel ball bearing itself played a seismic features, do not need to configure other devices on Pedestal, so low maintenance and management costs; seismic steel ball bearings in the size of the earthquake it does not produce residual deformation pot rubber bearing steel prices, but little change in the characteristics, without having to change; seismic steel ball bearing elastic properties depend on temperature is small, suitable for a wide range of areas; seismic steel ball branch creep characteristics of good seat, using a newly developed steel castings. Seismic steel ball bearing good creep resistance, using a newly developed steel castings. The surface-coated steel ball bearing seismic EPDM, rubber protection against internal ozone, effects of UV light, etc., with better anti-aging properties. Seismic steel ball bearing elastic stiffness (equivalent stiffness) is dependent on the size of the deformation, deformation hour stiffness, stiffness of large deformation is small, non-linear state. For wind load, high rigidity achieved initial braking function. For earthquakes, because the stiffness of large deformation is small, you can get a good shock effect. And, for excessive elastic deformation sales Pedestal, can cause hardening of rubber, rubber stiffness increases, you can expect to have control over the upper part of the structure of large displacement effects. Seismic steel ball bearing performance characteristics of the test, including test and seismic tests alone bearing steel, seismic test desirability scale of not less than one-quarter of the sample, after approval of the Engineer after.
