The spaces under bridge have been used as business zone and yard. The facilities and piles of goods under bridges are considered at high risk for fire danger. In this paper, CFD simulations were conducted to predict the temperature change beneath steel and concrete bridges due to fire in clothing boxes, frequently placed in the space under bridge. Based on these results, the relationship between the piled height of clothing boxes and the clearance of bridge, and temperatures beneath the bridge was derived using a Lagrange interpolation.
