福州数字中国会展中心楼盖舒适度分析及振动控制

Comfort analysis and vibration control of Fuzhou Digital China Conference and Exhibition Center

采用调谐质量消能器对福州数字中国会展中心的大跨度楼盖进行了舒适度分析和减振设计,对结构采用调谐质量消能器进行减振设计前后的舒适度进行对比分析,结果表明:减振前结构在人行荷载激励下大跨度楼盖不满足舒适度要求,采用调谐质量消能器后振动得到有效控制,满足舒适度要求。从而证明了调谐质量消能器能有效改善大跨度楼盖的舒适度,且具有良好的经济性与适用性,可在类似工程结构中进行推广和应用。

Comfort analysis and energy dissipation design are carried out for Fuzhou Digital China Conference and Exhibition Center,TMD(tuned mass damper)are used in large span floor.The vibration comfort analysis of energy dissipation design with TMD(tuned mass damper)indicates that the comfort of large span floor doesn*t meet with standard in all human-induced load cases before energy dissipation design,but the comfort of large span floor meets with standard in all load cases after energy dissipation design with TMD(tuned mass damper).The comfort of large span floor is effectively improved by TMD(tuned mass damper),which is economical and applicability,which can be applied in the similar large-span floor structure.
