• Abstract:
  This project introduces an innovative method that utilizes shape memory alloys (SMAs), a new class of smart materials, as transverse reinforcement in the end regions of precast prestressed concrete (PC) bridge girders. The proposed solution effectively addresses the long-standing issue of damage in the end regions of PC bridge girders caused by the application of prestressing force. SMA transverse reinforcement, known for its shape recovery capability, can help prevent cracking in these critical areas while reducing the congestion of steel reinforcement typically found in highly reinforced sections of bridge girders. The project involved both numerical and experimental studies to investigate damage mitigation during the release of prestress in PC girders. This was achieved by placing transverse SMA bars within the concrete at the end regions of the girders and generating the prestressing force through SMA activation. The results validate the effectiveness of this new reinforcement method in reducing and healing damage in the end regions of PC bridge girders.
