The response is studied in relatively light equipment components subjected to short-duration ground shock and impact and earthquake ground shaking. The object of the study is to develop analytical results which can easily be used to determine equipment response and which offer an alternative to costly standard numerical integration schemes and to various ad-hoc methods in current use. A description is given of classical perturbation theory, considered as a tool in the analysis of equipment-structure systems. This theory is then applied in the modeling of the equipment-structure system as a two degree-of-freedom system.
