摘　　要：为研究阻尼器在结构中的优化布置及其减震效果,以某5层医技楼为例,将46个消能支撑体系逐层渐变地安装在原结构上,采用弹性时程分析方法对建筑模型进行计算。通过对减震与非减震结构层间位移角、层间剪力及结构底部剪力的对比,对阻尼器典型滞回曲线的分析得出附加的粘滞阻尼器在地震下拥有饱满的滞回曲线,能够充分发挥减震耗能作用。工程主体结构增设粘滞阻尼器后,很好地减少了地震响应,结构的抗震性能有了较大的提升。In order to study the optimal arrangement of dampers in the structure and its seismic effect,the author took a five-storey medical building as an example,installing 46 energy dissipation support systems gradually on the original structure,and calculating the building model by the elastic time history analysis method.Based on the comparison ofinterlayer displacement angle,interlayer shear and bottom shear,the typical hysteretic curve of dampers was analyzed.The results showed that the additional viscous damper has a full hysteretic curve under the earthquake,which can give full play to the role of energy dissipation.After adding viscous dampers to the main structure of the project,the seismic response is greatly reduced and the seismic performance of the structure is greatly improved.
