Abstract
The rapid expansion of high-strength concrete applications in construction and bridges. When using high strength concrete, all methods of building can benefit from the beneficial benefits of reduced member sizes and strengthening. Bridges, on the other hand, are often built with long lengths, resulting in considerable dead weight, which, when combined with the creep and shrinkage properties of concrete, results in significant dead weight. In the long run, this results in major deformation and prestressing force depletion. The effects of creep and shrinkage on prestressed concrete bridge girders were studied in this report. The aim is to measure prestress failure in high-strength concrete bridges and to find justifications for expanding the use of high-strength concrete in bridge construction. The aim of this report is to forecast concrete's long-term creep and shrinkage activity. The development of generic prediction approaches that a design engineer can use when precise experimental data is unavailable. A literature review was also carried out as part of this research. It implies that high-strength concrete necessitates a change in current creep and shrinkage behavior. As a result, the first part of this research focuses on determining the correct creep and shrinkage code. The bridge case is then subjected to a finite element analysis. The findings show that the complex the complex effects of high strength concrete strength, creep, and shrinkage behavior on girder size and prestressing volume are controlled by the complex effects of high strength concrete strength, creep, and shrinkage behavior.
