Simple evaluation technique of environmental vibration with soilstructure interaction

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 soilstructure 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.
