摘要:
采用国家标准中普通薄层隔震橡胶支座的竖向刚度公式计算厚层橡胶隔震支座的竖向压缩刚度值,一般会偏大较多。通过对厚度橡胶支座进行竖向压缩静力试验研究的基础上,运用ABQUES大型通用有限元软件对影响厚层橡胶支座竖向刚度的相关参数进行了展开分析研究,探讨了各影响因素的变化规律,提出竖向刚度公式修正公式,并将此竖向刚度公式与其他竖向刚度公式进行对比。结果表明,当厚层橡胶支座第一形状系数小于7时,本文给出的厚层橡胶隔震支座的竖向压缩刚度公式可以给出相对比较准确的结果。
Abstract:
The vertical compression stiffness of thick rubber bearing calculated by using the vertical stiffness formula of ordinary thin layer rubber bearing in the national standard is generally larger than that of the thick layer rubber bearing. Based on the static test of vertical compression of thick rubber bearing, this paper analyzes and studies the related parameters affecting the vertical stiffness of thick rubber bearing by using ABQUES large general finite element software,discusses the variation law of each influencing factor,proposes the correction formula of vertical stiffness formula, and compares this vertical stiffness formula with other vertical stiffness formulas. The results show that when the first shape coefficient of the thick layer rubber bearing is less than 7, the vertical compression stiffness formula of the thick layer rubber isolation bearing given in this paper can give relatively accurate results.
