Abstract |
Applying fire resistive coating to steel members is one of the generally used methods to secure fire resistance performance of steel members. And spray-applied fire resistive coating is currently the most widely used method among those of giving fire resistance to steel members. Spray-applied fire resistive coating, however, has undesirable weaknesses in deteriorating fire resistance performance of steel members due to cracks and falling-offs of the coverings with passing time after completion of the coverings to the members. So it is necessary to understand changes of the fire resistance performance of the spray-applied fire resistive coating over a long- time elapse and to reflect the changes properly into the building design and construction. This study is designed to understand changes in fire resistance performance of spray-applied fire resistive coating through follow-up tests over 10 years period on temperature of unexposed surface of the domestic spray-applied fire resistive coating. And this study is to suggest estimated models on the fundamental fire resistance performance of the spray-applied fire resistive coating based on the test results over 10 years period. |
