| Abstract: | According to the dynamic features of isolation structures, the motion equation of torsional vibration in non-proportionally damped isolation structures is presented. The torsional vibration in these structures is analyzed, and the influences of the eccentricity of the system and super-structure on dynamic response are also discussed. |
