Analysis of Anchorage Behavior Characteristics of the Electrical Cabinet Using Shaking Table Tests

Abstract

In this study, a shaking table test was performed to analyze the anchor behavior with or without rocking in the base plate of an electric cabinet. Two cabinets, differentiated by whether their base plates were anchored or fixed, were mounted simultaneously on a shaking table to enable a comparison of their behavior when subjected to seismic motion. Three seismic waves were used in this experiment to facilitate temporal history and resonance search. Results indicated that the impact load occurred due to mutual collision with the local mode of the cabinets’ internal components. Moreover, in the case of a single-door cabinet with a bolt fastening, it was observed that rocking mode occurred due to upliftment of the base plate. To address this problem the cabinet was tested again after being reinforced and the results achieved before and after the reinforcement procedure were discussed.
