| Outline of Final Research Achievements |
For the sake of mitigation for suspended ceiling and facilities equipment, the experimental and numerical studies are done to clarify the characteristics of typical style of them. For suspended ceilings, two types of accurate or convenient numerical methods are suggested to calculate the displacement and stresses and the validation is shown by comparison with experimental results. Furthermore, the pulling out strength and the shear strength of screws which are used for ceiling board to be attached to steel furring, are clarified quantitatively. For facilities equipment, the low cycle fatigue of a hanging bolt is considered as an actual serious damage type and the condition for such damage is summarized. Furthermore, the behavior of facilities equipment with braces is examined through the shaking table test and it is shown that the low cycle fatigue is occurred and the usual connection type of braces has some problems.
