| Abstract: | The motion equations for the dynamic analysis of the base isolation structures in the time domain is established by using the finite scheme.Based on it the finite element program is drawn up taking into consideration of the hysteretic behavior of the isolation system.The dynamic response of the base isolation structures under ELCentro (NS.1940) ground motion excitation is evaluated.The computed results show that the acceleration response of the superstructure decreases. |
