【摘要】 某五层框架结构由于振动过大而影响其正常使用,通过有限元程序对结构进行了模态分析,计算得出了结构的自振频率及振型,并用现场实测结果验证了计算结果的准确性,从而为进一步振动控制提供参考.更多还原

【Abstract】 One building with five-layer frame structure as aresult of vibrated oversized affects its normal use,in this paper,taking nomal analysis of structure in the ANSYS,the computation has obtained the self-vibration frequecy and mode shapes of the structure,and has comfirmed the computed result accuracy on the spot with the actual result,thus to further vibration control provide the reference.更多还原
