This study attempts to develop
the accurate fire-driven flow beneath the historical arch bridge to obtain the
fire-related variables and specifications such as gas temperature and smoke and
flame behavior. Simulation of temporal fire behavior is mainly performed using Fire
Dynamic Simulator (FDS) based programs that use computational fluid dynamics
(CFD). In this regard, this study finds the accurate fire temperature values
for a case study historical arch bridge, Golcegiz stone arch bridge is located
in Tokat, Turkey. The length and width of the bridge are 26.65m and 5.35m
respectively. The fire simulation has been done concerning two different
scenarios: 1) the fire is located close to the bottom-right side of the bridge
2) the fire is located in the midpoint below the bridge. The analysis result
shows the maximum applied fire load is related to Scenario 1 with a maximum
value of 603°C. The values obtained from surface temperature measurements can
be used in the finite element software to perform the thermal-structural
analysis of this bridge.
