带黏滞阻尼器结构振动台试验模型设计中,黏滞阻尼器的相似设计成为关键一王不。从既有理论分析入手,研究阻尼器最大出力和运动幅值保持不变的情况下,速度指数的变化对耗能的影响。以重庆某带黏滞阻尼器减震结构为原型结构,分别进行基于阻尼力等效原则和耗能能力等效原则的黏滞阻尼器相似设计,对比分析两种方法结果,分析基于耗能能力等效方法的优越性,以期为今后带黏滞阻尼器结构振动台试验模型设计提供参考。
Scale model design of viscous dampers is a key part of design for shaking table test model of a stucture with viscous dampers. Based on existing theoretical analysis, the effect of the velocity exponent change on energy dissipation capacity was studied under the condition that the maximum damping force and deformation of viscous dampers are kept constant. Based on a structure with viscous dampers in Chongqing ( seismic intensity 6) , the scale model for viscous dampers was designed following the equivalence of damping force and energy dissipation capacity, respectively. Advantages of the energy dissipation capacity - based method can be concluded from the comparison between the two methods.
