Abstract The study introduced a developed computer program named "PBridge," designed for the analysis and design of composite prestressed concrete bridges. This program was created using the Java programming language, with analyses and designs modeled according to the procedures outlined in Eurocode 1 2003, particularly Parts 2, EN 1991, Parts 1–4, and 1–5. The traffic load models, along with wind and temperature loads were the design load of the bridge. The design of the bridges were categorized into two types: single-span design with a main span of 25 meters and continuous-span design with a main span of 40 meters. Each direction of the proposed bridge features two notional traffic lanes of 3 meters each, accommodating a total carriageway width of 7.2 meters. For the single-span prestressed bridge, both manual calculations and the PBridge program yielded a requirement of 72 strands, while the continuous-span prestressed bridge required 96 strands, consistent across both methods. To further validate the accuracy of these results, Bending Moment and Shear Force results from ANSYS and PBridge were compared. The percentage difference in bending moment at 2.5 meters from the end support was 0.0013 for the single span, and 0.0066 for the continuous span at a distance of 5 meters from the end support. For shear force, the differences were 0.009 for the single span and 0.0228 for the continuous span at distances of 2.5 and 5.0 meters, respectively. These results indicate that the developed program can be reliably used for the analysis and design of prestressed concrete bridges.
