- Abstract
- [ABSTRACT IN ENGLISH] The water-filled tubular steel structure is known as one of the means to provide the steel structure with fire resistance. The water-filled tubular steel structure is fabricated of the steel framework consisting of hollow sections filled with water. This paper discusses the fire resistance of water-filled tubular steel structures by way of experimental and analysis results. Fire resistance tests were performed using the testing equipment as illustrated in Fig. 2 and by making a change in the total volume of water in a steel column, storage tank and pipe loop. Theoretical analysis was made by application of a traditional heat transfer equation. However, the heat transfer coefficient between the heated surface of steel column and surrounding gases was estimated using the equaiton (5.15). The heat transfer coefficient between the internal surface of steel column and filled water was assumed to be variable in accordance with the temperature of filled water as shown in Fig. 12.
