摘要
以第29届奥林匹克运动会铁人三项赛场为检测对象,通过对原设计整体结构加固及局部减振后以及原结构进行对比实验,得出了整体刚度有较大提高,局部减振措施效果良好的结果.根据Z振级测试分析,加固后竖向Z振级明显减小,说明采取加固减振措施后,振动对运动员比赛无影响.
Taking the 29th Olympic Games triathlon stadium as the testing object, through the comparative experiment for the original design of the overall structure strengthening and local damping after the original structure, it shows that the overall stiffness has improved greatly, and local measures has good effect. According to Z-level test analysis, the vertical Z-grade vibration is significantly reduced after reinforcement. It shows that the vibration has no effect to the athlets in the competition.
