摘　　要：以某偏心框架结构为研究对象,采用均匀分布、权系数分布、逐层逼近分布三种不同粘滞阻尼器的布置方式建立有限元模型,从层间位移角、楼层剪力和结构综合评价指标等角度,研究了不同布置方式对结构减震效果的影响。结果表明:逐层逼近分布减震控制效果最优,权分布布置又优于均匀分布布置;在操作简易程度和消耗时间上,权分布和均匀分布均优于逐层逼近布置,对于实际工程来说,权分布最为实用。An eccentric frame structure is studied and the finite element model is established by the arrangement of three kinds of viscous dampers with uniform distribution, weight coefficient distribution and layer-by-layer approximation distribution. The impact of different arrangements on the damping effect of the structure from the point of view of the story draft, the floor shear and the comprehensive evaluation index of the structure is analyzed. The results indicate that the hierarchy search distribution damping control has the best effect, and the weight coefficient distribution is better than the uniform distribution; In the ease of operation and time-consuming, the weight coefficient distribution and the uniform distribution are better than hierarchy search distribution. So the weight coefficient distribution is the most practical for practical engineering.
