    AI Summary
    • Level 2 Assessment:
      Network Rail U-Frame Steel Bridge with MIDAS Civil NX + FEA NX: Beyond Level 1: building a U-frame bridge finite element model from scratch, running linear static and buckling analyses, then a full geometric and material non-linear assessment.

    Description

    In this session, Vikrant will walk through a Level 2 assessment of a U-frame steel bridge — from building a shell model with the right materials, meshing and boundary  conditions to linear and non-linear assessment.

    Part 1: Introduction of FEA NX
    - Overview
    - Modelling and meshing
    - Supported analysis types

    Part 2: Modelling of U-Frame Bridge in FEA NX
    - Material and shell property definition
    - Modelling and meshing geometry
    - Boundary and loading conditions

    Part 3: Defining Analysis Cases
    - Linear static analysis
    - Linear buckling analysis
    - Results: displacements, von Mises stresses, buckling modes

    Part 4: Geometric and Material Non-Linear Analysis
    - Imperfections and construction stage sequencing
    - Geometric and material non-linear input
    - Result interpretation and conclusions

    Key Points

    Build a shell model with the right materials, meshing and boundary conditions

    Run linear static and linear buckling analyse

    Introduce imperfections and reach a defensible non-linear conclusion
