It is currently the largest diameter bearings applied to the base-isolated building in China. Composite damping isolation bearings, new damping supports, were used in the building for the first time. The static and dynamic mechanical properties were studied, and the stability and reliability for large-diameter bearings are obtained. It provides a useful reference for the popularization and application of the new damping supports in the future.Keywords:laminated rubber bearing; vertical compression performance; horizontal shear performance; damping bearings廣東省科技計劃項目(2004B10101048),(2005A11601014),(2006B37301009)；建設(shè)部科技計劃項目(2005K148),(2006K301),(2007K309)。作者簡介：張季超(1956),男,教授,Email：zhangjichao1956@126.com。參考文獻［1］周福霖.工程結(jié)構(gòu)減震控制［M］.北京:地震出版社,1997.［2］張敏政,孟慶利,裴強.疊層橡膠隔震支座的動態(tài)穩(wěn)定性和力學特性研究［J］.地震工程與工程振動,2002,22(5)：85-91.［3］周錫元,韓淼,馬東輝，等.疊層鋼板橡膠墊的穩(wěn)定性分析與強度驗算［J］.建筑科學,1997(6)：13-19.［4］蘇經(jīng)宇,韓淼,周錫元，等.橡膠支座基礎(chǔ)隔震建筑地震作用實用計算方法［J］.振動工程學報，1999,12(2)：82-89.
