Abstract
Ultra-High-Performance Concrete (UHPC) is increasingly utilized in highly stressed civil engineering structures (e.g., bridges) and is often bonded to existing UHPC structures for repair purposes. These bonded interfaces, however, often become the weakest points that are susceptible to cracking over time. Thus, accurate monitoring and measurement of crack propagation at these interfaces is crucial. To achieve this, this study employs digital image correlation (DIC), a non-contact displacement and strain measurement technique. As DIC becomes more prevalent in experimental mechanics and SHM, to promote practicality and economy of DIC monitoring of existing structures, a homography-based transform, compatible with open-source DIC software, was used as the primary rectification method for high stereo angle between cameras. Overall, this study aims to: (1) rectify large stereo angles between cameras to adapt to existing DIC open-source software; and (2) evaluate the accuracy with which DIC analysis captures deflection and strain near the UHPC-UHPC interface under flexural loading.

Notes
Not relating to joint program but here are some specifics about the submission:
1. Degree is Bachelors of Science in Civil Engineering (B.S.C.E), I didn't see an option for this within the drop-down.
2. PDF was generated through Overleaf LaTeX software. Through Adobe accessibility checker, the only violation is in character encoding, however, it corresponds to formula elements only that are vastly changed if I attempt to resolve the character encoding error, so I have left it be.
3. Dissemination option is intended to be dissemination with limited access to the UCF community for a period of one year.
