A Study on the Sound Insulation Performance of Steel-Structured Apartment Buildings (I)

철골조 공동주택의 차음성능 실태조사에 관한 연구 (I)

The sound insulation performance of walls and floors for air-borne and structure-borne sounds in an apartment building is an important environmental factor which should be contemplated at the intial design stage for their thorough control. Recent increasing residents' demands for quality living spaces strongly urge the development of more accurate and efficient measurement and evaluation methods for the control of air-borne and structure-borne sound insulation. However, steel-structured apartment buildings, recently emerged as new building structures in the market, have not been thoroughly examined. The present work carried out an extensive survey for steel-structured apartment buildings, in an attempt to provide useful design data, and their sound insulation performances were compared with those of R.C. apartment buildings.
