Abstract

This study aims to analyze the damage and destruction behavior of pallet racks due to external forces through shaking table test. Pallet racks is a general storage racks type consisting of column, beam, and brace to resist an external force. To analyze the safety of the pallet racks due to external force, a shaking table test was conducted to investigate the pallet racks behavior due to external force while increasing the seismic load targeting the pallet racks used in the existing logistics storage facility. As a result of the shaking table test, it was confirmed that the torsion of the pallet racks damaged the connection parts of some members located on the 1st and 2nd levels, thereby destroying the loading equipment.

본 연구에서는 진동대 실험을 통하여 지진하중으로 인한 팔레트 랙의 손상 및 파괴 거동을 분석하고자 하였다. 팔레트 랙은 일반적인 적재설비의 한 종류로써 기둥, 보, 그리고 브레이스로 구성되어 지진하중에 저항한다. 팔레트 랙의 지진하중으로 인한 안전성을 분석하기 위하여, 실제 물류저장 시설에서 사용되고 있는 팔레트 랙을 대상으로 지진하중을 증가시켜가면서 하중으로 인한 팔레트 랙의 거동을 분석하기 위한 진동대 실험을 진행하였다. 진동대 실험 결과, 팔레트 랙은 비틀림이 발생하면서, 1층과 2층에 위치한 일부 부재의 연결부가 손상되고, 그로 인하여 적재설비가 파괴되는 것이 확인되었다.
