Research and analysis on seismic isolation design of Hainan Library
The main structure system of the new east building and west building of Hainan Library is the frame structure.Taking the design process of the east building as an example,the research and analysis process of the seismic isolation design of this project was expounded.By comparing the mechanical performance,building space superiority,cost and construction structure of different structural schemes,the isolation scheme of basement column top was determined.According to the set isolation target,the isolation bearing was reasonably configured,and the reasonable seismic wave was selected to analyze it according to the requirements of Code for seismic design of buildings(GB 50011-2010).The results of seismic isolation analysis show that the isolation bearing meets the requirements of stress and deformation under different working conditions,the overall isolation design meets the preset isolation target requirements,and the structure is basically in elastic state under rare earthquakes.In addition,the key problems of the structural design of this project were discussed,including the isolation force characteristics of the basement column top,the torsion control effect and the analysis of the role of viscous dampers in the isolation structure.
