This paper describes a simple model for analyzing the acceleration response of an elevator-type high-rise mechanical parking system in a high-rise building. It is based on a previously proposed 3D model, and involves both Voigt model representing the rubber dampers, and bending-shear elements representing two types of columns. The validity of this model is verified by comparing the acceleration response obtained using the previously proposed 3D model, which is an important factor when considering the business continuity plan for such parking systems.
