[0003] In the design of the current friction pendulum seismic isolation support, the stainless steel sliding panel is fixed in the upper and lower plate grooves of the support by being slotted and using screws, but such a structure design reduces the displacement space of the support due to the presence of the screws. When the support moves, the spherical cap may hit the fixed screws on the stainless steel sliding panel, causing a large impact force. This impact force may damage the wear plate, making the support unable to reset and normally operate.
