STUDY ON APPLICATION OF NORMAL MODE SOLUTION TO PREDICTION OF GROUND ENVIRONMENTAL VIBRATION

Abstract

When predicting ground environmental vibrations, vibration analysis using the finite element method or the thin layer method is often used, but while these methods are capable of precise vibration prediction, they are computationally expensive. In general, most of ground environmental vibrations are caused by vibrating ground surfaces, and it is well known that surface waves are dominant compared to body waves. In this study, the transfer function obtained by ground shaking experiments was compared with the normal mode solution. Next, the normal mode solution was applied to the prediction of construction-induced vibration.
