| 摘 要： | 通过在距离隔震层一定位移处设置由弹簧和与其串联的限位挡板组成的变刚度保护装置作为第二道防线,成功地进行了五层框架的变刚度隔震保护模拟地震振动台试验。理论分析和试验结果表明,变刚度隔震保护装置能有效改变结构动力特性,减小隔震层的变形,使之限制在允许的范围内。

| Abstract: | In order to ensure the safety of base isolated buildings during extreme earthquakes,this paper provides a type of stiffness variable isolated protection device which is installed in certain distance from the protected rubber bearings as the second defence measure.And a shaking table test of a five-floor steel-frame model has been completed successfully in Beijing Polytechnic University.On the basis of theory and shaking table test research,the stiffness variable isolated protection device can effectively reduce the horizontal deformation to prescribed limitation and prevent the rubber bearings from failure because the dynamic character of the structure has been changed,and the story shear forces of the super-structure are only slightly increased. |
