| contents | This study presents the development of a computer program called "PBridge" for the analysis and design of prestressed I-beam concrete bridges. Prestressed concrete is increasingly used in bridge design worldwide because it can supportsignificant loads and is resilient to the effects of wind and temperature variations throughout its lifespan. The analysesand designs were modelled based on Eurocode design procedures. The bridge model features a continuous-span designwith a main span of 40 meters. Each of the two side spans consists of a 7.2-meter carriageway, including two notionaltraffic lanes of 3 meters each, in both directions. The proposed bridge is expected to span a freshwater river, such as theRiver Niger in Onitsha, Anambra State, Nigeria. The total initial prestress force of 13770 kN and the total prestress forceof 18749 kN were derived using 96 strands for the continuous-span prestressed bridge for both manual calculations andPBridge results. The selected prestressed strands, Y1860S7G with a diameter of 12.7 mm (7-wire drawn strands), werefound to be adequate for this continuous span. To further validate the results, the bending moment and shear forceoutcomes from both STAAD Pro and PBridge were compared for the continuous span. The percentage difference for thebending moment was 0.0044 at a distance of 5 meters from the end support, while for shear force, it was 0.0034 at thesame distance. These findings indicate that the developed program can be reliably used for the analysis and design ofprestressed concrete bridges. |
