Numerical Simulation of Forced Vibration Tests on a Buried Arch.

Abstract

Finite element simulation of a buried arch structure shows that the effective damping depends on backfill conditions. This information is used to explain the occurrence of resonance in forced vibration tests of buried rectangular structures and its absence in tests of the arch. Implications of the findings for developing single degree of freedom models of complex structures are examined. (Author)
