Analysis of behavioral characteristics according to the fixing condition of pallet rack

Abstract

This study aims to verify the damage and collapse of the pallet rack due to external forces, such as earthquakes, through a shake table test and analyze the behavioral characteristics of the pallet rack column foundation for each fixing condition caused by a continuous external force. A shake table test was conducted on a pallet rack commonly used in warehouses to examine its damage and collapse owing to external forces. In the shake table test, the strength of the load was increased to investigate the collapse of the pallet rack, and the failure of the member connection was regarded as a collapse. The behavioral characteristics were analyzed using the shake table test according to the conditions of the baseplate connections, which are determined by the external forces. The displacements caused by the external force, permanent displacement, cumulative displacement, and damage were analyzed from the data obtained through the experiment. Finally, the possibility of collapse according to the fixing condition was verified.
