Importance of Rigid-Body Motions on a Single-Degree-of-Freedom Model

Abstract

The study presents the effect of rigid body motion on the single- degree-of-freedom (SDOF) model presently used for dynamic analyses of buried roof slabs. The effect of rigid body motion is incorporated by adding a second degree of freedom to the model. Relative displacements between the roof and the structure are given for comparison. The results indicate that at overpressures required to cause severe damage to a relatively hard, shallow buried structure, rigid body motion will have little effect on the damage predicted from an SDOF analysis. Keywords: Soil structure interactions; Mathematical prediction.
