The serviceability limit state of structures is subject to increasing attention. Flooring-systems may encounter vertical vibrations that may be perceived as annoying by stationary persons sitting or standing on the structure. This paper looks into human induced floor vibration of a 33-storey residential building by using theoretical analysis and in-situ inspection. The results show that though the vertical eigenfrequency of the floor satisfies the demand of vibration comfort stated in the Technical Specification for Concrete Structures of Tall Buildings (JGJ3-2010), the maximum value of vertical vibration of the floor system is excessively large, which is caused by the stiffness shortage of the floor due to the decreased floor thickness.
