| 摘 要： | 针对某型钢混凝土框支剪力墙高层建筑结构高宽比过大、竖向刚度不规则等问题,采用耗能减震技术,在转换层与避难层处设置黏滞阻尼器,采用ETABS进行非线性动力时程分析,研究黏滞阻尼器对型钢混凝土框支剪力墙结构的地震和风荷载控制作用,提高型钢混凝土转换构件的抗震性能。研究结果表明,在不同地震动作用下黏滞阻尼器均能有效地降低型钢混凝土框支剪力墙结构的地震响应,结构峰值位移和最大层间位移角的减幅分别介于3%～45%和2%～43%,而黏滞阻尼器耗散总输入能量比例最高达73.65%;在风荷载时程作用下,结构各控制楼层的峰值位移减幅介于1%～11%之间。 |

| Abstract: | Considering the problem that the height-width ratio is too large and the vertical stiffness is irregular on the high-rise building of steel reinforced concrete frame-supported shear wall structure,installing the viscous damper(VD) on transfer and refuge story is proposed.By using ETABS program,nonlinear dynamic time history analysis is carried out to study the seismic responses of the structure under earthquake and wind actions.The results show that the viscous damper can effectively reduce the seismic structural responses under earthquake.The reduction of peak displacement and largest inter-story drift angle is between 3% to 45% and 2% to 43%.respectively The proportion of total input energy dissipated is up to 73.65%.The peak displacement reduction of all control story is between 1% to 11% under the wind load action. |
