【 摘 要 】

In order to investigate the isolation performance and economic advantages of different period isolation structures, the isolation design and analysis of different period isolation structures are carried out with an office building as the background, and the related structure, structural design and engineering economy are discussed. Time history analysis shows that under the action of 8 degree earthquake, the isolation performance of short-period isolation structure is better than that of long-period isolation structure; engineering economic analysis shows that when the tensile stress exceeds the limit of the isolation bearing, special measures are needed for adjustment. Will result in a substantial increase in project cost.
