| Abstract |
A low-rise steel-framed house system has been developing as a construction pattern at domestic residential construction since the late of 1990 in Korea. The major structural elements such as load-bearing walls and floor-assembles were made up of light gauge steels around 1.0mm in thickness and light weight construction materials such as gypsum boards, plywoods and etc. Nowadays, the steel framed house systems built with light gauge steels and light weight construction materials have been trying to develop a new application such as the low rise apartments or building below 4 stories and the likes. In order to meet the building regulation in aspects of fire resistance of buildings mentioned above, a proper fire resistance system is requested. For the satisfaction of building regulation in terms of fire resistance and to support of the safer structural elements such as load bearing walls and floor ceiling assembles in fire, we have conducted heat transfer analyses and fire resistance tests with walls and floor-assembles. All specimens equipped with 2 layers of Type X were shown over 1 hour fire resistance endurance. |
