ABSTRACT:

This paper presents the results of time history analysis of steel school buildings damaged by 2016 Kumamoto Earthquakes. A comparison between three buildings in the same site with different plans and directions employed to investigate the seismic behavior of floor and ceiling system. These three-story buildings were built in 1982 after the introduction of Japanese current seismic design code. Based on the past seismic requirements after the construction, the seismic reinforcements for suspended ceilings were made in 2012. The failure of ceiling systems occurred in North building created debris hazard. In comparison with North Building, The damage of other two buildings occurred in smaller events. The deformations and the accelerations on the floors obtained from the analysis of three buildings were compared with each other. These standardized school buildings with suspended ceiling system have the same structure and facilities. 3D-FEM models depending on these building axes and the structural components were created. Using these FEM models, the damages of the ceilings have been compared with the analysis response on the locations in the buildings.
