600型建筑叠层橡胶隔震装置温度相关性及耐老化性能研究

Research on Temperature Dependence and Aging Rigidity of 600 Laminated Steel-plate-laminated-rubber-bearing Isolation Bearings for Building

摘要: 采用600型建筑叠层橡胶隔震装置为研究体,系统地研究了其温度为(-20℃~40℃)时的特性;温度为100℃时,恒温时间240 h和336 h状态下老化特性;老化前后相关性能对比;老化后极限性能及120次反复循环加载后的基准性能.结果表明:温度对叠层橡胶隔震装置的竖向刚度、水平刚度、屈服力及等效阻尼比具有不同程度的影响;其耐老化寿命可达到60 a;为隔震技术在建筑领域中推广应用提供了依据.

Abstract: In this research,the temperature dependence of laminated rubber damping bearing with temperature from -20 ℃ to +40 ℃ are tested for 600 laminated rubber damping bearing.With the temperature of 100 ℃ from 240 to 336 hours,in front and behind aging and 120 times recycled pressurization of laminated rubber damping bearing are compared by property.It is proved that the temperature influence laminated rubber damping bearing with damping ratio and horizontal and vertical stiffness.Its' aging tests are attained to 60 years with the temperature of 20 ℃,providing foundation for isolators technique using in the field of architecture.
