| 【摘要】 | 主要研究设置粘滞阻尼器的连体高层结构风振响应及风动力荷载作用下粘滞阻尼器对结构内力、变形、加速度及能量耗散的控制效果。根据连体高层结构刚性模型的风洞试验，得到风压系数时程数据。通过编制基于风洞试验的风荷载时程处理程序WINDHIST V2.0，可将风洞试验数据进行处理并导入有限元程序进行风振时程分析。对连体高层结构进行多工况风振时程分析，结果显示：设置粘滞阻尼器能减小连体结构内力及变形，内力的控制效果优于变形的控制效果。连体结构顶部加速度是由脉动风的动力效应引起，粘滞阻尼器能有效地控制结构顶部楼层加速度。 |
| 【英文摘要】 | This Paper involves wind-induced vibration analysis of a connected tall building structure with viscous damper. The control effect of viscous damper in several respects, such as internal force, deformation, acceleration and energy under dynamic wind load is studied. Firstly, wind pressure time-history data is gained from the wind-tunnel test of the structure model, and then a wind load processing program WINDHIST V2.0 based on wind tunnel test is programmed, by which wind pressure data can be processed and inputted into FEM program. Thus wind-induced vibration time-history analysis under various cases could be realized. The results show that both the internal force and deformation of the connected structure with viscous damper can be decreased, while the effect of the former is more obvious than the latter. The acceleration at the top of the connected structure caused by dynamic response of fluctuating wind can be controlled effectively by viscous damper. |
