Role of Soil Hysteresis in Impedance Testing as Applied to Buried Arches

Abstract

The effect of backfill soil hysteretic damping upon the suppression of resonance for buried arches is examined. Finite element simulation of a buried arch structure shows that the backfill soil hysteretic behavior is a dominant factor in explaining the absence of resonance in arch tests. Keywords: Structure-medium interaction, Finite element simulation, Hysteretic damping.
