An Experimental Study on the Fire Resistance of Wall-Slab Connection at High Temperature

Abstract

In recent years, fire has frequently occurred in domestic buildings. Therefore, interest in fire-protection design of buildings is increasing. Unlike fires in buildings such as shops and offices, fires on important structures such as Nuclear Power Plants(NPPs) are important both nationally and globally. The ‘Fukushima Nuclear Accident’ that occurred in March 2011 increased the need to maintain structural integrity of important structures such as Nuclear Power Plants. Even now, data on the structural behavior of large and important structures such as NPPs in the ‘during fire’ or ‘after fire’ have been lacking. It is essential to obtain fire resistance characteristics and to predict structural behavior through the analysis and theory because it is limited to experiment equipment and specifications to perform the actual fire and structural test on the large structures such as structures applied to the NPPs. Therefore, in this study, the 'Wall-Slab Connection(WSC)' test specimen used in EPR was fabricated. For the fire test, the specimen was heated by the furnace using the ASTM E119 standard fire curve.
