［摘要］中新天津生態(tài)城十二年制學校工程位于8度區(qū)（0-3g），對其中的教學樓和體育館建筑進行了隔震設計，采用基礎隔震形式，設置了355個隔震支座、211個U形鋼棒阻尼器、58個黏滯阻尼器，是目前國內(nèi)首次將U形鋼棒阻尼器應用于隔震建筑的項目。隔震分析中計算了中震減震效果，并采用ABAQUS軟件對隔震結(jié)構進行了大震作用下的驗算。計算分析表明，采取隔震措施可顯著降低上部結(jié)構的地震作用，解決扭轉(zhuǎn)不規(guī)則問題，優(yōu)化建筑布置。

Abstract:The 12-year-consecutive compulsory school in Sino-Singapore Tianjin Eco-city is located in region of 8 degree of seismic intensity with seismic acceleration of 0-3g. Isolation design was conducted on the teaching building and gymnasium building of the school, and the base isolation form was adopted with 355 isolation bearings, 211 U-shaped steel rod dampers and 58 viscous dampers. The project features the first application of U-shaped steel rod damper in isolated building in China. The seismic isolation effect under fortification earthquake was calculated in seismic isolation analysis, and ABAQUS software was used to calculate the seismic isolation structure under rare earthquake. The calculation and analysis show that the seismic isolation measure can significantly reduce the earthquake action on upper structure, which can solve the problem of irregular torsion and optimize the building arrangement.
Keywords:isolation bearing; U-shaped steel rod damper; ABAQUS; elasto-plastic analysis
