Imaging Tools for Evaluation of Gusset Plate Connections in Steel Truss Bridges

There are four main objectives of the proposed research: (1) Develop methods to collect dimensional gusset plate connection information including surface geometry and out-of-plane deformations on in-service gusset plates. (2) Develop methods to automate identification and optimization of reference target points. Develop methods to automate extraction of gusset plate edge locations, fastener locations and their corresponding member affiliations, and member orientations. (3) Develop finite element modeling and analysis techniques to directly rate gusset plates using extracted digital image data as the input source. (4) Develop software tools to manage and organize images and image data to enhance bridge management and allow identification of condition changes over time.
