Dynamic Response of Embedded Structures.

Abstract

Structures that have to resist impact loading are often designed to be embedded under soil backfill. The backfill attenuates the external surface load and decreases the free field stresses at the level of the structure. Physical mechanisms which are associated with the soil-structure interaction further affect the loading and response of the structure, and are important to understand for better, more efficient design of these structures. The response to an external surface impact of a structure with a reinforced concrete roof, embedded in a shallow depth of burial, was studied here. The research employed an experimental investigation of a small scale radial model and numerical analysis based on the finite element method to evaluate the mechanisms associated with the experimental results.
