Abstract
The seismic reinforcing system is developed to prevent damage to electric panels which are installed on the access floor and are essential to the operation of various basic facilities such as electric power and communication etc., from earthquakes. The seismic capacity of seismic reinforcing system is verified through the shaking table test. The seismic reinforcing system is intended for the electric panel on the access floor, and installation is possible without movement and power interruption of the electric panel. The enveloped response spectrum is adopted considering the location of the electric panel in the building as input motion for the shaking table test. The shaking table tests are carried out with two electric panels that can be considered representative of general electric panels, and two types of access floors such as wood panel and steel panel, which are commonly used in the industrial field. As a result of tests, it is confirmed that the seismic reinforcing system secures the seismic safety of electric panels by preventing the overturning of electric panels during and after the shaking table tests. In the event that the seismic reinforcing system is applied to the electric panel on the access floor, damage to the electric panel from an earthquake can be effectively prevented, which can greatly contribute to the stable operation of domestic basic facilities.
