In this study, fire resistance test according to KS F 2257-8: 2015 was carried out to compare fire resistance for wall consisted of gypsum boards with two types of drywall with gypsum boards which is based to lightweight studs. As a result, it was found that the fire resistance of the wall constructed with 12.5 mm of general gypsum board was 16 minutes higher than that of the wall constructed 9.5 mm in accordance with integrity and was 9 minutes higher than that of the wall(9.5 mm) depending on insulation. If the wall with the gypsum board 12.5 mm is constructed, it can be confirmed that the fire resistance is improved by about 43%.

공동주택을 기둥식 구조에서 공간을 구획하는 비내력 벽체로 사용되는 경략벽체에 요구되어지는 다양한 성능조건 중 내화성능 기준을 등급으로 구분하여 제시하고자 한다. 공동주택 경량벽체를 세대간 벽과 세대내 벽으로 구분하여 각각의 내화성능 요구수준에 맞는 성능등급을 설정하였으며, 이를 내화실험을 통하여 성능을 확인하였다.

Recently, the structure system for apartment buildings in Korea has been changing from wall to post-beam structure. This study examines the fire resistance and sound insulation of light-weight dried wall, a component of post-beam structure. For the fire resistance and sound insulation in Korea, the Compartment wall of apartment house in the case of building regulation has regulations specify the detailed requirement of fire compartment walls in apartment, but do not specify that of interior walls. This study proposes the fire resisting rate of the interior wall into three grades in which the highest grade requires fire resistance of 30 minutes and also proposes the requirement of sound insulation performance into three grades in which the lowest grade requires 35dB.

As being inconvenient to apply reinforced concrete structure to high-rise buildings, it is applied steel structured system. Therefore light-weight wall systems are applied as partition wall to reduce the self-load of the building. But, the required performances of a light-weight wall are not evaluated systematically. As a field survey result, partition walls of house-to-house were not showed their respected performances, so the dwellers are feel so worse the quality of the whole building. In steel-structured high-rise buildings especially, occupant's dissatisfaction concerned indoor noise was high because curtain wall systems having a high air-tight performance isolate the outdoor noise making masking effect. Therefore wall systems which have high performances of sound insulation and air-tightness are required in high-rise buildings. As a result, a new drywall system was presented and the performance was verified with field test.
