Strengthening and Rehabilitation of U-Shaped RC Bridges Using Substitute Cable Ducts

Figure 11

The basic scheme of prestressing static effect on the simple span bridge (reduction of dead load bending moments—application of LBM). Prestressing creates a much bigger reserve of bearing capacity which can be used for traffic load, and therefore, the load-bearing capacity is increased. The efficiency of this method is up to 300%.
