SIMPLE EVALUATION TECHNIQUE OF ENVIRONMENTAL VIBRATION WITH SOIL-STRUCTURE INTERACTION

Abstract

Prior to construction of facilities which should not be exposed to intense environmental vibration, it is advisable to measure in-situ vibration and verify design merit to meet the environmental criteria. We have constructed simple response evaluation technique with soil-structure interaction incorporated. This technique comprises dynamic spring evaluated for simple soil layers identified by micro-tremor array observation and foundation input motion by spatial integration of measured accelerations. An application to the real site reveals similar results to that of FEM with energy transmitting boundary.
