| 摘 要： | 考虑主体结构与顶部幕墙结构的相互作用,采用主体结构层模型-顶部幕墙结构杆系模型分析结构的风效应和顶部幕墙的风振鞭梢效应,应用增设内置式粘弹性阻尼器支撑的控制方法来减小顶部幕墙的风振响应.通过对一栋42层的高层建筑的计算分析表明:采用内置式粘弹性阻尼器支撑后,大大地降低顶部幕墙结构的风振位移,为防止顶部玻璃幕墙的掉落增加可靠性.

| Abstract: | In consideration of the interaction of the main structure and top curtain wall,the wind response of the tall building and top curtain wall are calculated while the main structure is simplified as a layer model and top curtain wall is simplified as a truss model.The wind-induced whipping effect of top curtain wall is prevented by using viscoelastic dampers which is installed inside the original steel tube.The work on a 42-floor building shows the inside-installing viscoelastic dampers can significantly reduce the wind-induced displacement,and prevent the collapse of top curtain wall. |
