| Abstract |
The sub-micro vibration problem in technology facility has been important as essential factor having an effect on performance of manufactures. To design long-span of production lines with increasing the manufacture equipment is essentially demanded in the most recent, accordingly a matter of concern about vibration isolation also is growing. While international competitive power of internal electronic and IT industry maintains the highest level, technical know-how of facilities field in technology facility has depended on a developed country. Therefore, there is a need of total analysis to design the long-span structure system on industrial demand of technology facility and to improve the vibration isolation level. In this study, we research dynamic characteristics and vibration response of floor system in the design of long-span structure system and would like to propose an alternative proposal to improve sub-micro vibration isolation level. In the study result, when return plenum floor stiffness is increased in order to reduce vibration of floor system, we can make certain of vibration reduction effect from increasing slab thickness of return plenum, changing the number of beam and a design plan and increasing section size of beam. |
