Abstract: |
The problem of bridge fire is growing. Because of bad experience in Warsaw, Poland local government decided to prove fire resistance of all bridge structures across Vistula river which pass through the city. One of such bridges is six spans continuous truss – 400 m long - with double deck: upper is concrete highway deck and lower is timber tramway deck. Possibility of occurrence of fire on tramway bridge with timber deck inclined the owner of the bridge to exchange whole deck and sleepers in particular. Because the load capacity of the bridge was drew out it was not possible to apply steel or concrete sleepers. Therefore the owner decided to fit up synthetic wood sleepers. To be sure that this kind of sleepers mounted on the bridge is safe special research program was introduced. The results of investigation proofed good structural material properties and good fire resistance of sleepers. Proposal of new structural solution of the bridge is also given. |
