Course Smart Rail Structure Interaction (RSI) for Metro Viaducts

Explore Rail–Structure Interaction (RSI) for metro viaducts, from fundamental behaviour and design requirements to practical nonlinear analysis and automation. Learn how temperature, braking, traction, vertical train loads, track behaviour, support stiffness, and bridge configuration influence rail stresses and displacements. Practical case studies cover U-girder viaducts, station structures, mixed superstructures, special spans, and complex multi-track configurations. The webinar demonstrates simplified and staged nonlinear RSI analysis using bilinear track springs, together with validation against a UIC example. An Excel-based approach automates bridge geometry, loading and analysis input and generates reports containing rail stresses, displacements and support reactions.
