Vibration testing for dynamic properties of building floors

Abstract: The paper presents a comparison of testing methods and post processing techniques for modal properties of a fully furnished chipboard floor and an unfurnished prestressed concrete floor. A thorough modal testing required relocation of transducers among test setups to acquire multiple synchronous measurements of floor response due to heel drop excitation or shaker excitation. The comprehensive experimental data was processed by a specialised operational modal analysis software. On the other hand, a simple testi… Show more

“…On the other hand, resonance would be less important compared with transient response in a high-frequency floor with a fundamental frequency greater than 9-10 Hz [8][9][10]14]. The damping ratio of a floor, which represents the vibrational energy dissipation, depends not only on the material and structural type but also on the architectural components and nonstructural elements attached to the floor [15,16]. Cao et al tested a long-span prestressed concrete floor to be used in the lounge of a major airport.…”

“…However, the damping level of a floor is much more difficult to evaluate as the damping depends not only on the material and construction type of structural members but also on the non-structural elements or architectural components attached to the floor. Some types of dynamic testing such as include heel drop impact, hammer impact and forced vibration testing with an electrodynamic shaker can be utilized to estimate the floor modal properties including the damping ratio [16]. Alternatively, it is possible to refer to the damping values given in current guidelines for typical floor structures constructed from different material with different levels of furnishing.…”
