Abstract

In this study, the first research based structural fire resistance test of a steel-concrete composite floor in Turkey is conducted and the ultimate goal is to fill the knowledge gaps in the current Turkish building code for the structural fire engineering and provide valuable insight for the development of new theoretical, computational and experimental research. The tested composite floor is specifically designed for a high-rise steel building. The floor is equipped with a patent pending mechanism to provide symmetric boundary conditions on two edges. The floor is subjected to ISO-834 standard fire curve from the bottom surface for 105 minutes followed by 90 minutes cooling. Displacement and temperature measurements show that at elevated temperatures, the concrete slab carries the load by the tensile membrane action without a contribution of the secondary beam. This study suggests that secondary steel beams do not need to be fire protected as the concrete slab is adequate to carry the gravity loading during fire
