| Abstract: | The basic structure and the seismic isolation principle of the friction pendulum bearing(FPB) are introduced.The theoretical analysis study on FPB based on the principle of mechanical equilibrium is conducted. The stiffness and the effective viscous damping ratio of FPB are derived and also the hysteretic model is constructed,while its recovery mechanism is discussed and the computing formula of maximum residual displacement is obtained as well.Moreover,the model with solid element of FPB is built by using ... |
