| Abstract |
Non-structural elements are vulnerable to earthquake ground motion. In this study, an experimental study for the electrical non-structural
element was performed using tri-axial shaking table tests. A 100kVA UPS(Uninterruptible Power Supply system) was used as the test
specimen. The test specimen was anchored to the concrete slab using the conventional installation detail. The input acceleration were
generated in accordance with ICC-ES AC156 code. Scale factors of the input acceleration with respect to the required response spectrum
defined in ICC-ES AC156 were from 25% to 600%. Based on the test results, damage and dynamic characteristics of UPS were evaluated
and analyzed including natural frequency, damping ratio, acceleration time history response, dynamic amplification factor and relative
displacement. |
