This session focuses on understanding how contact behavior affects the performance and safety of arch bridges, especially at critical lug and pin connections. Using MIDAS FEA NX, the session walks through nonlinear static contact analysis, demonstrates a real lug-pin connection model, and explains how engineers can evaluate stress transfer, local deformation, and potential failure points. Practical case examples and real-world collapse scenarios are also discussed to highlight why accurate contact modeling is essential in bridge design and assessment.
