［摘要］在進行有氧健身操時，某健身房的樓板振動非常明顯，參加健身運動和周圍的人群感覺很不舒服，經(jīng)復(fù)核，樓板振動不滿足舒適度要求。為此，加固設(shè)計采用了替換次梁和在主梁下翼緣貼鋼板的加固方案，使樓板振動控制達到了舒適度的要求。通過該工程實例，詳細(xì)說明了在有氧健身操等有節(jié)奏運動作用下樓板振動的計算方法和加固方法，可為類似工程提供參考。

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
