Introduction Of Flat-Spring Friction System For Seismic Isolation

An innovative seismic isolation technique known as the flat-spring friction system (FFS) for seismic isolation was developed in this study. This novel isolation technique has some distinct features, such as improved upliftrestraint safety, higher vertical sustaining force, extended environmental duration, and variable frequency, which can be intuitively observed by readers. A series of analytical and numerical investigations were conducted to verify the seismic isolation performance of the FFS. An algorithm for the FFS was developed, and a multistorey structural model was established. Seven earthquake records were selected as the input to shake the structural model. The numerical simulation results showed that the structural response could be significantly reduced when the FFS was installed as isolators.
