对近断层地震作用下连接相邻结构的非线性黏滞流体阻尼器的控制效果和性能进行了研究.根据阻尼器布置位置的不同共定义了3种分析工况.首先确定了各工况耦联结构耗能体系的动力响应;其次通过参数化研究得到了各工况中阻尼器的优化阻尼系数;最后基于阻尼器的最大输出力和最大冲程,对阻尼器的性能进行了详细的评价.研究表明:不同布置方式下阻尼器的优化阻尼系数大致相同;目前的技术条件可以满足不同布置方式下所需阻尼器的最大输出力和最大冲程.
The control effect and performance of the nonlinear viscous fluid damper connected with adjacent structures under near-fault earthquake are studied. According to the different positions of the dampers, three kinds of analysis conditions are defined. Firstly, Then the optimal damping coefficient of the damper in each working condition is obtained through parametric research. Finally, the damper performance is evaluated in detail based on the maximum output force and the maximum stroke of the damper. The results show that the optimal damping coefficients of the dampers under different layouts are approximately the same. The current technical conditions can meet the maximum output force and the maximum stroke of the dampers required under different layouts.
