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

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.
