| 摘 要： | 通过现场实测，根据实测结果分析了受动荷载作用的钢筋混凝土多层框架结构厂房楼面产生较大竖向振幅的原因，对其进行了结构加固设计，包括对楼面结构主梁、次梁、楼板及下一层柱子的加固处理，根据施工完毕后的实测结果分析，楼面竖向振动幅度大大降低，达到了减振的目的。

| Abstract: | According to the field measurement results, the reasons of vertical vibration of the floor of a multilstory reinforced concrete frame factory building are analyzed, the strennthening design is performed, including the strengthening design of the 3rd floor beams and columns in the 2nd story. After the construction is completed, another field measurement for the factory building strengthened is also carried out, the tested results show that the peak vertical displacement decreases greatly, and the intention of vibration reduction is achieved. |
