Evaluation of the floor vibration of concrete structures

Abstract

The safety of concrete slab was evaluated based on the floor vibration impact sound. The research of high dependability was accomplished for appraisal of floor vibration form applying evaluation standard of serviceability of Reiher/Meister with Koch and evaluation standard of vibration of ISO and AIJ. Test of twice was using different accelerometers, and it was accomplished such as FFT from comparative analysis of the vibration standard. Result of vibration impact sound measurement, peak displacement of Test 1 is in the range of 0.00869∼0.02540 mm, the value of peak frequency is in the range of 18∼27 Hz, average is 22 Hz. The peak acceleration value of Test 2 is in the range of 0.47∼1.07%g, the value of peak frequency is 18.5∼22.57 Hz, average is 21 Hz. The vibration was apparently recognizable in most cases, according to the Reiher/Meister and Koch. Evaluation of serviceability is following the vibration standard and residential appraisal guidelines provided by of ISO and AIJ.
