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广东省科技计划项目(2004B10101048),(2005A11601014),(2006B37301009)；建设部科技计划项目(2005K148),(2006K301),(2007K309)。作者简介：张季超(1956),男,教授,Email：zhangjichao1956@126.com。参考文献［1］周福霖.工程结构减震控制［M］.北京:地震出版社,1997.［2］张敏政,孟庆利,裴强.叠层橡胶隔震支座的动态稳定性和力学特性研究［J］.地震工程与工程振动,2002,22(5)：85-91.［3］周锡元,韩淼,马东辉，等.叠层钢板橡胶垫的稳定性分析与强度验算［J］.建筑科学,1997(6)：13-19.［4］苏经宇,韩淼,周锡元，等.橡胶支座基础隔震建筑地震作用实用计算方法［J］.振动工程学报，1999,12(2)：82-89.
