This paper intends to analyze the behavior characteristics of steel storage racks according to the constraints conditions by external loads such as seismic loads. In order to achieve these goals, the steel storage racks generally used in Korea were selected as target structures and shaking table tests were conducted. In order to confirm the behavior according to the constraints conditions, the foundation of the steel storage racks was constructed with three conditions (1 bolt, 4 bolts, fixed) and the experiment was carried out. As a result of the analysis of the data obtained through the experiment, it was confirmed that additional damper installation is needed rather than changing the condition of the bottom plate in order to secure the safety of the steel storage racks.
