| 摘 要： | 通过有限元分析,计算出原型结构中黏滞阻尼器的合理参数,然后利用阻尼力相似原则,对原型结构中黏滞阻尼器参数进行相似比运算,转化为模型结构中的黏滞阻尼器参数.运用该方法,在连续梁桥纵向消能减震振动台试验中设计模型黏滞阻尼器,从试验结果来看,黏滞阻尼器发挥了良好的消能减震效果.

| Abstract: | By the analysis of finite elements,the authors computed the viscous damper parameters of prototype structure.Then we used the similarity principle of damping force to calculate the ratio of similitude operation for the viscous damper parameters of prototype structure.It can be transformed into the viscous damper parameter of model structure.We used this method to design viscous dampers in the shaking table model test of continuous girder bridge with longitudinal seismic energy dissipation.The research results indicate that the viscous damper has a significant effect on seismic energy dissipation. |
