某展厅悬挑结构舒适度计算

Comfort calculation of cantilever structure in an exhibition hall

该工程中的大跨度悬挑结构,在人行激励荷载下,端部最大竖向振动加速度不符合预定的目标。采用质量调谐阻尼器(TMD)进行振动控制,计算结果表明,结构在步行荷载激励下的竖向加速度峰值有明显的降低,满足规范限值要求。

For the large-span cantilever structure in this project,under the pedestrian excitation load,the maximum vertical vibration acceleration at the end does not meet the predetermined goal. Tuned Mass Damper( TMD) is used for vibration control. The results show that the peak value of vertical acceleration of the structure under walking load excitation is significantly reduced,which meets the requirements of the code limit.
