［摘要］在进行有氧健身操时，某健身房的楼板振动非常明显，参加健身运动和周围的人群感觉很不舒服，经复核，楼板振动不满足舒适度要求。为此，加固设计采用了替换次梁和在主梁下翼缘贴钢板的加固方案，使楼板振动控制达到了舒适度的要求。通过该工程实例，详细说明了在有氧健身操等有节奏运动作用下楼板振动的计算方法和加固方法，可为类似工程提供参考。

Abstract:The floor vibration is obvious due to aerobic activities in a gymnasium.The people feel very uncomfortable.According to the calculation, the floor vibration can not meet the need of comfort. To meet the need of comfort,the joists were adopted and the girders were strengthened by welding a steel plate to the bottom flange.The calculation method and retrofit design of the floor vibration due to rhythmic activities were elaborated in detail. It may be refered to similar cases.
Keywords:rhythmic activity; floor vibration; comfort; retrofit
