摘　　要：根据现场实测结果,分析了受动荷栽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.结构加固后,为检测加固后的减振效果,对加固后结构再次进行了实地测试,通过对两次实测结果的对 比分析,结果表明:经加固后楼面竖向振动幅度大大降低,达到其减振目的.According to the measuring result in situ, the reason of vibration on a floor of a certain multilayer reinforced concrete frame factory is analyzed. After it is strengthened, vibration measuring also has been done. Results before strengthened and those after strengthened are analyzed, and the latter results are far less than the former, so the intention to decrease vertical vibration has been achieved.

关 键 词：厂房 竖向振动 测试 减振
