Abstract

Abstract

In order to investigate the fire resistance of double-skin multi-cavity composite wall with steel truss, two specimens were tested exposed to one-side ISO-834 standard fire. A specimen was unprotected and the other was protected by thick coated fireproof coating with a thickness of 20 mm. The test results indicated that: 1)the bare specimen reached the fire resistance limit due to the failure of thermal insulation; 2)the thickness of fireproof coating had a significant effect on the fire resistance limit. The specimen with fire protection had a fire resistance limit of more than 180 minutes which was at least twice as long as the specimen without fire protection.
