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

摘要

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.
