摘要:
与普通橡胶隔震支座不同,橡胶隔振支座单层橡胶较厚,竖向刚度随竖向面压增加而增大.橡胶隔振支座侧向变形采用矩形模拟,推导了侧向变形计算公式,并与试验作了对比,与试验结果接近.采用经典弹性力学理论,推导了1竖向刚度计算公式,得出了竖向刚度与竖向变形关系,并对橡胶隔振进行了竖向刚度试验验证.最后对橡胶隔振支座的疲劳性能进行了试验研究,结果表明,橡胶隔振支座具有良好的疲劳性能.
Abstract:
Unlike laminated rubber seismic isolation bearings,rubber vibration isolation bearings have a thicker single layer of rubber,and the vertical stiffness increases with the increase of vertical load.The lateral deformation profile of the rubber vibration isolation bearing is modeled in a rectangular shape,the lateral deformation calculation formula is derived and compared with the test results,and the theoretical calculation formula is close to the test results.Then,the vertical stiffness calculation formulas related to vertical deformation are deduced by the classical elasticity theory and verified by vertical stiffness tests.Finally,the fatigue performance test is performed on the rubber vibration isolation bearing,and the results show that the rubber vibration isolation bearing has good fatigue performance.
