Abstract:
One of the major problems faced in the transport industry today is the maintenance, repair and strengthening of deteriorating concrete bridges. Moreover, there is an urgent need to upgrade existing bridges that are now considered inadequate due to increase in traffic load requirements for bridge design. In this regard, external prestressing has the potential to be one of the most powerful techniques for strengthening and rehabilitating existing concrete bridges. A preliminary experimental investigation is being carried out to study the effectiveness of external prestressing for flexural strengthening of existing concrete bridges by conducting test on model beams. The results of this preliminary investigation are discussed in this paper, demonstrating that external prestressing is a viable solution for strengthening of existing bridges.
