摘要
奥林匹克国家会议中心大宴会厅L4桁架跨度大,人正常行走、跳跃时容易产生共振,中间跨中的加速度超过人体舒适度的要求,经计算、分析确定采用TMD粘滞流体阻尼器的减振方案。试验表明TMD-粘滞流体阻尼器的减振效果非常明显,为今后类似工程积累了宝贵的经验和试验数据。
In constructing the banquet hall of the National Conference Center Project, due to the big span of IA truss, person＇s normal walk and jump may result in resonance, and the acceleration on the intermediate trusses exceeds the comfort index of human body. After calculation and analysis, it was determined that TMD viscous fluid damper program would be used for vibration absorption. Test shows that this damper can absorb vibration effectively, providing some good experiences and test data for similar projects in the future.
