| 2. | In addition , in other to estimate systematically the stiffness property of isolating bearing , a series of basic concepts , such as origin compression stiffness , origin longitudinal compression elastic modulus , biasing pressure vertical stiffness , etc . are suggested with corresponding theoretical formula and testing estimation method 此外,为系统地评价隔震支座的刚度特性,提出了原点压缩刚度、原点纵压缩弹性模量、偏压竖向刚度等基本概念,同时还提出了相应的理论计算式和试验评价方法。 |
