Abstract
As part of a study to establish a performance-based fire-response design and evaluation method for logistics facilities, an experimental rack was manufactured, and the temperatures at the top of the combustible material during a rack fire were measured. The temperature time and temperature flame length relationships were established. Based on the variation in – – temperature with the arrangement of the combustibles, the rate of increase in heat flow through the vertical flue was higher when the combustibles were doubled than when they were single, indicating that the increased rate of the flame and flume was more than twice that of a single combustible. Based on the type of combustible, CEP exhibited a significantly higher rate of temperature increase than CUP. In the case of the CUP, when arranged in one stage and one row, the fire intensity was weak in the early stage of the fire; therefore, it was possible that the upper sprinkler head did not respond. In addition, the correlation between the flame length and temperature during the initial fire was relatively high (R<sup>2</sup> = 0.93).
