目前新疆高烈度地区隔震、减震技术的应用越来越多。位于新疆乌鲁木齐市设防烈度8度的某中学教学楼结构采用框架结构体系,属于乙类建筑。今采用基础隔震技术,在结构基础设置带有铅芯叠层橡胶支座的隔震层,经对其进行分析,表明进行隔震设计能够明显延长结构基本周期,可有效降低地震作用,使抗震设防烈度降低一级,能实现在中震作用下结构处于弹性阶段,罕遇地震作用下具有良好的变形性能。 At present, the application of seismic isolation and shock absorption technologies in high-intensity areas in Xinjiang is increasing. The structure of a middle school teaching building located in the 8th degree of fortification intensity in Urumqi, Xinjiang, adopts a framework structure system and belongs to the category B architecture. The use of base-isolated technology and the installation of a seismic isolation layer with lead-laminated rubber bearings on the structural basis have been analyzed. It shows that the isolation design can significantly prolong the basic cycle of the structure, and can effectively reduce the earthquake effect. The seismic fortification intensity is reduced by one level, and the structure can be realized in the elastic stage under the action of moderate earthquakes, and has good deformation performance under rare earthquakes.
