| Research Abstract |
In this project, the mechanical characteristics of ceiling and sprinkler systems which have had serious damages in the recent earthquakes are examined through results by experimental tests and numerical analyses. Particularly, we clarify the mechanical characteristics of joint metal parts in the steel furring of ceiling, the natural period of ceiling, the compressive strength of a ceiling surface and the fatigue behavior of plumbing in a sprinkler system quantitatively. Furthermore, the numerical method to simulate such systems accurately is developed in this project.
