摘要

采用现场试验的方法，对地铁附近某高层框架结构办公楼的室内振动进行了研究。研究结果表明:室外点振动加速度有效值平均值为0.003893 m/s2，且随着楼层的上升，建筑物室内振动呈现波动规律，且在中、高层振动放大。室外振动主要分布在50Hz~80Hz，峰值频率为63Hz，室内振动在40Hz以上明显减小，在35Hz以下放大。

Indoor vibration of a high-rise frame structure office building near metro lines

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.
