Three-Span Curved Steel Composite Bridge Design to CSA S6

In this quest, you will model a three-span curved steel composite I-girder bridge in MIDAS CIVIL NX. You will define plan and vertical curves, superelevation, variable girder sections, cross frames, piers, permanent loads, and staged deck construction. You will apply CSA S6-19 moving loads and evaluate deformations, member forces, and critical vehicle positions. Finally, you will perform curved steel composite girder design and RC pier design checks according to the Canadian bridge design standard. By completing this quest, you will learn how to: - Model a curved steel composite bridge with horizontal and vertical alignment data - Define superelevation, variable sections, cross frames, and pier geometry - Configure deck-pouring stages and composite section activation - Apply Canadian moving loads and identify critical vehicle positions - Define curved-bridge parameters, including girder radius - Check unbraced lengths, stiffeners, shear connectors, and fatigue - Perform CSA S6-19 steel girder and RC pier design checks
