The indoor vibration of a high-rise frame structure office building near the subway is studied using the method of field test. The research results show that the average value of the vibration acceleration effective value of outdoor point is 0.003893 m/s2 , and with the rise of the floor, the indoor vibration of the building shows a fluctuation law, and the vibration is amplified in the middle and high floors. The vibration outdoor is mainly distributed in 50Hz~80Hz, and the peak frequency is 63Hz, and the indoor vibration is significantly reduced above 40Hz, while amplified below 35Hz.
