Abstract

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.
