  • Based on the theoretical analysis and the finite element numerical calculation,the impact analysis of vibration-suppressed effectiveness of core-wall suspension isolation structure caused by dynamic parameter was made.A calculation method for the damping coefficient of the core-wall suspended structure was set up,under action of earthquake,the change law of damping coefficient of displacement and absolute acceleration,the vibration-suppressed effectiveness of core-wall suspension isolation structure caused by mass ratio and frequency ratio was also quantified.Research showed that the vibration-suppressed effectiveness of the relative displacement and absolute acceleration of the suspension isolated structure with bearings was stronger than the traditional suspension structure.It must ensure that mass ratio and frequency ratio should be in a certain range,which then could avoid resonance effect of the suspended structure happening and get an ideal vibration-suppressed effectiveness.
