摘要
文章对普通橡胶缓冲装置进行了性能试验并得到装置的力—变形曲线,在试验的基础上提出了缓冲装置的计算模型,并给出相应的设计方法.采用动力时程分析方法对设计方法的有效性进行了验证,并对其耗能和不耗能的计算模型进行了研究对比,研究表明本设计方法可以为缓冲装置的设计提供参考.
Pounding among girders is one of the main reasons for bridge damages during earthquake. The performance of the dampers is tested to propose the design method in this paper. According to the results of experiment, the design method of rubber type bumper devices is presented, and the validity of the method is verified with dynamic time history analysis, the mitigation pounding effect of calculating models for compression bumpers with or without energy dissipating is compared, and the results evidence that the design methods of bumper device are effective.
