| Abstract: |
The rehabilitation works on the five span continuous Warren type steel truss bridge built in 1961 have been presented in the paper. Because of steel structure deterioration and huge live loads growth during recent years, the bridge has been selected for the comprehensive rehabilitation with a main goal to increase its load carrying capacity. Apart from the strengthening of truss girders (f.e. member sections enlargement, external prestressing, rivet replacement, etc.), the rehabilitation also included deck grid extension, redecking of deteriorated concrete slab and upgrading of supports. The repair program for existing steel structure contained among others the replacement of two diagonals deformed by impact of vehicles. The rehabilitation procedure has been presented in the paper as well as the proof load test results, which proved rehabilitation efficiency. |
