Abstract
The main purpose of this study is to assess the safety of the fixed earthquake anchorages for the distribution panel of facilities in an actual power plant. Experimental and analytical studies were conducted to investigate the load response that occurs on the anchorages in the event of an actual earthquake. Shaking table experiments of the panels were first conducted and the boundary conditions of different joint connections were considered depending on the fabrication characteristics of the subject structure for a 3D finite element analysis modeling proposal. Therefore, the contribution of this study was to investigate the transfer load characteristics of the anchorages of the switchboard field installation according to the seismic wave characteristics through a comparison with a vibration band experiment and the three-dimensional finite element analysis modeling presented through this study. Using the verified analysis model, an additional finite element analysis was performed to check the dynamic behavior of anchor bolts under various loading conditions such as weight changes and other earthquake waves.
