There are many studies about concrete filled steel tube without fire protection. But there is very little study about the columns with separating walls that divide the fire compartment. Designer often planed that type of columns. But the no fire protection columns easily transfer the heat from the room in which fire occurs. This report mentions the experimental study about those columns. The authors used 12 concrete filled steel tubes for the test specimen. Each specimen has compartment wall, or fire protection, various size of cooling mass on the side. They are heated from one side, measuring the steel tube temperature of unheated side. From the test, appropriate thickness of cooling mass, or fire separating wall, or fire protection can control unexposed surface temperature under the temperature that causes fire spread.
