老化和徐变性能是LRB橡胶隔震支座重要的长期性能指标,对建筑LRB600原型橡胶支座进行了老化和15MPa持续加载下的徐变性能测试试验。测得了隔震橡胶支座初始状态和相当于60a后的热老化力学特性变化率,以及橡胶支座在1330h持续荷载作用下的徐变量。最后,基于测试结果提出了橡胶支座在正常使用状态下的徐变率预测方程。 Aging and creep properties are important long-term performance indicators of LRB rubber bearings. The LRB600 prototype rubber bearings were tested for aging and creep performance under a continuous load of 15 MPa. The initial state of isolated rubber bearings and the rate of change of thermal aging mechanical properties after 60 years were measured, and the creep of rubber bearings under continuous load of 1330h was measured. Finally, based on the test results, the creep rate prediction equation of rubber bearing under normal use condition is proposed.
