| 摘 要： | 汶川医院采用现浇钢筋混凝土框架结构,考虑其功能重要、结构不规则、抗震要求高等特点,在四周设置了46个K型粘滞阻尼器支撑,通过ETABS计算分析表明设置阻尼器能显著降低结构的响应,提高结构抗震性能,最后讨论了计算粘滞阻尼器结构附加阻尼比的简化使用算法。

| Abstract: | Wenchuan hospital structural system is reinforced concrete frame with viscous dampers,which has an irregular shape and a high seismic performance demand and 46 viscous dampers connected with K-braces are set along the outside surface of structure.Elastic analysis of structure with viscous dampers are carried out using ETABS.The comparison between dynamic analysis of structure with and without viscous dampers shows that structure responses can be effectively reduced by adding viscous dampers and the performa... |
