공동주택에서 내부진동의 전달특성에 관한 연구 ( Propagation Characteristics of Indoor Vibration in Apartment buildings )

Internal Vibration generated in buildings and propagated in every part of building through building structures affects building, people and percise machine in buildings. The purpose of this study suggests that the basic data for appropriate estimation method and reduction plan against internal vibration, propagation characteristics and coherence estimation generated from equipment machinery in apartment houses. The results of this study show that internal vibration is propagated from machinery room to indoor bathroom through each walls. Bibration level of wall by the machinery vibration was higher than that of ISO recommendation in machinery room and basement.
