高层结构三维基础隔震抗倾覆试验研究
|
摘要
为拓宽基础隔震技术的应用范围,开发了一种三维隔震抗倾覆支座并对其进行了试验研究。介绍了该支座的设计制作,通过拟静力试验研究其水平向和竖向力学性能。将该支座安装在一高层钢框架模型结构底部,输入不同场地不同峰值加速度的地震动激励,进行了有无三维隔震抗倾覆支座的地震模拟振动台对比试验,测试了模型结构的动力特性、加速度和位移反应以及基底剪力反应等。试验及分析结果表明:该支座具有较好的稳定性和较强的可靠性,结构在8度罕遇烈度地震作用下仍然是安全的;支座对结构在所给4条不同场地地震动作用下的动力反应有着良好的控制效果,且受输入加速度峰值的影响小。
In order to enlarge the application range of base isolation technology,a new three-dimensional base isolation and overturn resistance device(3D-BIORD) was developed and relevant experimental studies were carried out.Design process of the device is introduced.Based on the pseudo-static tests,horizontal and vertical mechanical properties of the device were studied.The 3D-BIORDs were installed on the bottom of a high-rise steel structural model,and then shaking table tests for comparison between the uncontrolled structure and the controlled structure were performed.Ground motions of different site types and acceleration amplitudes were input from the shaking table to the upper structural model.Dynamic characteristics,acceleration and displacement responses and base shear reactions of the model were measured.The experimental and analytical results show that 3D-BIORDs are of good stability and strong reliability,the structure is still safe under rare earthquake action of intensity 8 degree.The device has favorable control effects for the dynamic responses of the structure under the action of the four ground motions of different site types,and the acceleration amplitude has little influence on the control effect.
