Abstract: The subway-induced vibration response of the nearby buildings along Guangzhou Metro Line 3 was inves-tigated via site measurement，and the vibration propagation in buildings was numerically analyzed． The results show that (1) in frame structures，the vibration peak decreases with the increase of building height; (2) the subway-in-duced vibration frequency varies from 30 to 80Hz，mainly in the range of 30 ～50Hz; (3) the vibration reduction of the internal structure column is more significant than that of surrounding columns; (4) more beams on the column may result in greater energy loss; and (5) the acceleration caused by subway vibration may have an impact on the comfort level of people in buildings．

Key words: subway vibration, building structure, vibration response
