| Abstract |
In this study, a full scale 3-axes shake table test for M-bar and T-bar type ceilings commonly used in the country was conducted. Through
damage inspection during the test, seismic performance of ceilings according to variables, such as clearance between wall mold and ceiling as
well as existence of facilities, was evaluated. A test frame consisted of square hollow section members was used for the shake table test.
The experimental method was performed as a fragility test using required response spectrum described in ICC-ES AC156. In the case of
architectural nonstructural component that contain ceilings, it mainly is evaluated the performance by post-test visual inspection. For the
evaluation of seismic performance of ceilings, this study classified and defined damaged items for targeted ceiling system referring to
illustrative damage according to nonstructural performance levels accordance with ASCE 41 and previous studies. And proposed illustrative
damage items classification was utilized to compare the degree of the damage according to experimental variables. The experiment results
confirmed that differences in boundary conditions due to the clearance at wall mold and the installation of facilities had a significant effect
on the seismic performance of the ceiling. |
