Study on Aseismic Performance of Integrated Ceiling System and Anti-Fall Measures of Ceiling

Abstract eng:
Effective anti-fall devices of ceiling panels for an integrated ceiling system was proposed. A line-type integrated ceiling system was studied, because damage (falls of the panels) of the ceiling systems was widely observed during the 2011 off the Pacific coast of Tohoku Earthquake in Japan, which were used in many buildings completed before 1995. Especially, the damage of the ceiling system was widely observed in the Shinjuku campus building of Kogakuin University during the Tohoku Earthquake, which is a 29 stories of steel framed high-rise building and was completed in 1989. The ceiling damage situation was investigated along with acceleration records of the building. In addition, the composition and the actual installation situation of the ceiling system in the building were described, and the falling mechanism of a ceiling panel in the integrated ceiling system was investigated. Consequently, an effective anti-fall devices of ceiling panels using reinforcing hardware was proposed. Shaking table experiments of the ceiling system were conducted to reproduce the falling mechanism, and to confirm the performance of the anti-fall devices.
