Long-term Behavior of Prestressed Bridge After Reconstruction & Strengthening by P-T
Original language description
The paper presents the reconstruction process of a single-track railway bridge with five spans, put into operation in 1961 on the Czech railway line. The reconstruction was realized in 2009. The original superstructure from precast post-tensioned beams was reinforced by composite slab-shaped channel with a continuous gravel ballast. Due to the increase of self-weight and the requirement for strengthening the structure for the effect of modern rail traffic loading, the structure was reinforced by free additional prestressing cables. Long-term monitoring of the structure has been carried out over a period of ten years to verify the project's assumptions in terms of service life and to demonstrate the suitability of the technology for the rehabilitation of similar prestressed bridges that were used quite extensively in the Czech Republic in the 1960s and 1970s. The second part of the paper also deals with the issues related to the evaluation of long-term monitoring of concrete bridges after reconstructio
