STUDY ABOUT THE SIMPLE EVALUATION TECHNIQUE OF THE ENVIRONMENTAL VIBRATION WITH WAVE EQUATION

In environmental vibration evaluation, a simple evaluation technique based on sub-structure-type lumped mass model is proposed. The technique was applied to real site to show the comparative performance with the advanced technique based on 3D-FEM. The response evaluated by simple technique tends to be smaller than that by advanced technique particularly in high frequency, however, this technique is convenient and may be advantageous for in-situ examination for low frequency with a consideration on some safety factors.
