Overview
In this quest, you will model a single-span steel composite I-girder bridge using the Steel Composite Bridge Wizard in MIDAS CIVIL NX. You will define steel and concrete materials, time-dependent properties, composite girder sections, cross bracing, permanent loads, and construction stages. You will then apply static and AASHTO moving loads and review reactions, member forces, stresses, and critical vehicle positions. Finally, you will perform steel composite design according to AASHTO LRFD 2020 and load rating according to AASHTO LRFR 2019. By completing this quest, you will learn how to: - Generate a steel composite I-girder bridge model - Configure composite sections, bracing, loads, and construction stages - Define AASHTO moving-load cases and identify critical vehicle positions - Check flexure, lateral-torsional buckling, fatigue, and deflection - Define transverse stiffeners and shear connectors - Perform LRFR rating and generate design and rating reports
