摘要
利用美国惠普ＨＰ３５６７０Ａ型双通道动态信号分析仪对高层建筑结构的自振频率进行测量，并对测量结果进行功率谱、功率谱密度转换，经频谱分析等得出该建筑结构的自振频率，并将测试结果与近似公式的计算结果相比较，基本吻合。
We tested the self vibration frequency of high construction applying HP35670A Dynamic Analyzer,changed test results into power spectrum and power spectrum density,and gained the building’s self vibration frequency through frequency spectrum.By comparison,we found that it corresponds to the calculation result of similar equation.
