| Abstract |
In Korea, the seismic design of non-structural elements was interested by Earthquake of the 2016 Gyeong-ju and 2017 Po-hang. Among the
non-structural elements, the ceiling system with steel panel used in Po-hang station showed failure examples of non-seismic design ceiling. In
this study, the seismic performance of suspended ceiling with steel-panel, such as those used in Po-hang Station, was evaluated by shaking
table tests. The shaking table tests were performed in accordance with the ICC-ES AC156 standard with floor acceleration being applied
horizontally in one direction using a 3.3 × 3.3 m2 frame. The ceiling system consists of steel-panels, carrying channels, main and cross
T-bars, and anti-falling clips. The anti-falling clip prevents the steel panel falling completely. The shaking table test confirmed that the
damage at the previous stage had a direct impact on the damage state at the next stage. Through the shaking table test, the damage state of
the T-bar type steel-panel suspended ceiling system was defined. |
