Application and study of seismic isolation in the Kunming new airport terminal building

摘要

The main building, i.e. the kernel area of the Kunming new airport terminal is an import and complex structure, and it is located in the area with high seismic risks. To this end, seismic isolation techniques were applied to the building structure. The seismic isolation layer was set between the basement and platform of piles, and three kinds of isolation devices, i.e. natural rubber bearing, lead rubber bearing, and viscous damper were adopted. Analysis and design details are presented in the paper. The analysis and design results suggest that satisfactory seismic isolation effects can be achieved for the important and complex structure.
