摘　　要：对不等高双塔连体建筑上海国际设计中心进行了结构自振频率和阻尼比的脉动法现场实测,并对实测结果运用SVSA2.0软件进行数据处理分析,最后将分析结果与设计软件分析结果和振动台模型试验结果进行对比。研究发现主塔楼和副塔楼在长轴方向能够较好地共同工作,而在短轴方向协同性较差。脉动法实测自振周期与其他方法分析结果较接近,实测阻尼比小于规范建议值。The Shanghai International Design Center is a multi-tower building of different heights. Natural pe-riods and damping ratios of the structure were obtained by using ambinent vibration tests. The results from the tests were compared with design values and shaking table tests. Test results show that the two towers can work together on the long axis （X axis） and is unable to work integratedly on the short axis （Y axis）. Natural peri-ods from the ambinet vibration test are close to the results of other methods, and damping ratios from the test are smaller than the recommended value in the code.
