Influence of the Isolated Layer Damping Distribution of the Lateral-Torsional Coupling Isolated System on Earthquake Response

Abstract:

On the basis of the simplified model of lateral-torsional coupling isolated structure, dynamic equations of non-proportional damping isolated system of lateral-torsional coupling is established, and the influence of the isolated layer and the superstructure damping dynamic parameters on earthquake response is calculated and analyzed. The results show that, by reasonable adjustment of the damping distribution of the isolated layer, the torsion effect of the superstructure can be significantly reduced, and the basis displacement as well as rotation can be better suppressed, providing a basis for the design of the isolated layer damper reasonable distribution.
