[提要] 某鋼筋混凝土框架結(jié)構(gòu)廠房將兩臺選粉機置于樓面,選粉機的水平旋轉(zhuǎn)引起結(jié)構(gòu)沿縱向發(fā)生過大的水平振動?,F(xiàn)場測試了房屋的動力性能及各層樓面的水平位移,進行了結(jié)構(gòu)動力計算,分析了結(jié)構(gòu)振動的原因,并對振動危害程度作出了評價,提出了降低振動影響的措施。
[關(guān)鍵詞] 框架結(jié)構(gòu) 振動 測試 分析 鑒定Horizontal vibration was caused significantly along the longitudinal direction of a reinforced concrete frame by two rotatory equiments. The dynamic parameters of the structure are measured, and the dynamic evaluation of the frame is made. Through the vibratory analysis of the frame, the degree of the harm of vibration is assessed, and the measures are presented to reduce the influence of the vibration.
