BEHAVIOR OF FIRE PROTECTIONS IN A COLLAPSE TEST OF A FULL SCALE 4-STORY STEEL BUILDING

Abstract

Fire resistance of structures depends on the structural stability during a fire.
If a fire occurs in a building after an earthquake, structural members would lose their stability earlier than the nominal fire resistance time because the fire protection would be damaged by the earthquake. This paper shows the deformation behavior of the fire protections which comprise covering with sprayed rock wool, calcium silicate board, heat-resisting rock wool blanket, and heat-resistance coating sheet in shaking table tests on a full-scale steel structure. As a result of the tests, the fire protections were little damaged about efficiency of fire resistive performance.
