A Brief Technical Analysis Of The Engineering Practice With Isolation Technology

After "Wenchuan earthquake", isolation technique in earthquake-prone regions acrossthe country to get promoted, Urumqi is one of them. But due to the isolation technology formost of the domestic engineering design personnel is very strange, makes it hard for isolationtechnology to apply in the engineering practice, isolation technique further promote ishampered by a lot.Based on the No.1Middle School in Urumqi isolation structure design as an example,mainly expounds the following three issues:The first on the one hand: through the finite element analysis software ETABS program,respectively on the base isolation pillars isolation with the basement nonlinear time historyanalysis, determined for the purpose of this project, the basement pillars isolation dampingeffect is better than that of base isolation;Second aspect: the structure of the basement pillars isolation in detail design, introducesthe design of vibration isolation structure basic flow, determine its feasibility, and putsforward some problems that should be paid attention to in isolation design;Third aspect: pillars in the basement isolation design, on the whole model and theselection of the whole model are analyzed; In addition, the isolation in the design of practicalengineering problems of some of the more troubling, settings and pillar pull beam under pillarand foundation of the reasonable design problems put forward some views.
