| Abstract |
|
The buildings constructed with steel structure is coated with certified Sprayed Fire Resistive Material(SFRM) to resist from fire. All the building materials lose their initial performances as time passes, so they need durability. This study covers standardization of the methods for assessing the durability of SFRM. In Korea, more than 90 percent of SFRM are used indoors. So their fire performance were tested under indoor conditions before and after accelerate wet/dry cycling and temperature cycling to standardize the methods for assessing their durability. |

철골 건축물은 화재시 안전확보를 위하여 인정 받은 내화뿜칠재로 피복을 한다. 내화뿜칠피복재도 다른 건축자재와 같이 시간이 경과함에 따라 초기의 성능이 저하되어 내구성이 필요하다. 본 연구에서는 내화뿜칠재의 90% 이상이 실내에서 사용됨에 착안하여, 냉온조건, 건습조건에 따른 내화뿜칠피복재의 촉진내구성 평가방법을 제시하였다. |
