Seismic Response Analysis on Two-Tower Isolated Structure with Enlarged Base

Abstract:

In this paper, the three-dimensional finite element method has been adopted to respectively establish the base isolation of the two-tower structure with enlarged base and the story-isolated vibration analysis model. Each model has been conducted the elastic-plastic time-history analysis under the horizontal earthquakes. The results show that the dynamic characteristics of the structure have been significantly changed through the arrangement of isolation layer; the seismic responses, such as the story drift, the seismic shear and the acceleration of the structure, have been also greatly affected and the damping effect of the structure is obvious.
