摘　　要： 以高烈度区某含较多短柱的钢筋混凝土框架结构为研究对象,针对结构短柱受剪承载力及弹性层间位移角不满足规范要求问题,采用非线性黏滞阻尼器对该框架结构进行减震设计,进行了多遇和罕遇地震作用下的非线性时程分析。分析结果表明,设置非线性黏滞阻尼器后,有效降低了短柱剪力,使之满足规范受剪承载力设计要求;结构层间位移角显著减小,多遇和罕遇地震作用下的最大减震效果分别为56.43%和28.32%,非线性黏滞阻尼器在多遇和罕遇地震作用下均具有良好的耗能能力。 In order to solve the problem that shear resistant capacity and elastic inter-story drift angle of the short column fail to meet the requirements of code,the reinforced concrete frame structure with many short columns in high seismic fortification intensity zone was adopted as the study object. The damping design with non-linear viscous dampers was carried out on the frame as well as nonlinear time-history analysis under the frequent and rare earthquakes. Analysis results indicate that the shear resistant capacity of the short column reduces effectively with nonlinear viscous dampers and meets requirements of the code. The structural inter-story drift angle reduces significantly. Under the frequent and rare earthquakes,the maximum damping effects are 56. 43% and 28. 32% respectively. Therefore well energy dissipation ability of the non-linear viscous damper can be found under the frequent and rare earthquakes.
