| Abstract: |
Road traffic fires may have critical impact on long span bridges. Especially for suspension bridges, critical damages on the main cable and the tower can be fatal and practically not be repairable / replaceable. In Osman Gazi Bridge in Turkey, which has the main span of 1,550m and opened for traffic on 1st of July, 2016, the necessity of fire protection on the main cable was revealed through the risk analysis with ALARP principle so as to keep the temperature of main cable below 400oC against HGV (Heavy Good Vehicle) fires or hazardous materials fires, where those flame temperatures can reach up to 1,200oC. Through several trials for details, an active fire protection was selected to protect the main cable. It is the first application for the suspension bridge in the world and the paper introduces the result of risk analysis, design, trial and application of the fire protection system for the main cable of Osman Gazi bridge. |
