隔震橡胶支座竖向刚度和水平力学性能研究
Research on Vertical Stiffness and Horizontal Properties of Rubber Bearings
【摘要】 对我国隔震橡胶支座作了竖向刚度分析,结果表明铅芯橡胶支座的竖向刚度理论值与试 验值吻合极好,普通橡胶支座试验值则偏小;同时对我国橡胶支座水平性能进行了回归研究,得 出了水平有效刚度回归公式。
【Abstract】 The rubber bearing vertical stiffness is first studied in this paper. The test results of Chinese lead rubber bearing vertical stiffness are approximate to the calculated from the recent theoretical formulas. However, the test results of normal rubber bearing are lower to the theory calcuated. In addition, this paper discusses the horizontal proper of Chinese rubber bearings, and the horizontal stiffness formulas are also fetched through the test results.
