Abstract:

As the long-span prestressed concrete floors are widely used in stadiums, buildings with large open space and high buildings, the vertical vibration serviceability is becoming increasingly important. So the research of long-span prestressed concrete floor vertical vibration under pedestrian loads has great significance. According to practical engineering, the study presented the vibration measurement scheme and the vibration signal was detected by high sensitivity piezoelectric accelerometer, we got the first two order frequencies of the floor vertical vibration and the corresponding damping ratios by mode-superposition method. Also, finite element models were established to simulate the floor vertical vibration. Based on the comparison between the numerical results and the corresponding measurements, the most appropriate model was determined for studying the dynamic behavior of long-span prestressed floors.
