    Webinar Overview
    Post-tensioned precast I-girder bridges are among the most widely adopted superstructure systems in modern highway infrastructure. Their efficiency, durability, and constructability make them a preferred solution for medium to long-span bridge projects worldwide.

    This webinar delivers a complete engineering workflow—from structural idealization and tendon profiling to load combinations, prestress loss calculations, section adequacy checks, and results interpretation entirely within MIDAS CIVIL NX following AASHTO LRFD provisions. Participants will gain practical, hands-on insight into how advanced finite element tools streamline code-compliant bridge design and improve professional accuracy on real projects.
    What Attendees Will Learn
    — Model a post-tensioned precast I-girder bridge in MIDAS CIVIL NX
    — Develop tendon profiles and perform construction stage analysis
    — Apply AASHTO LRFD load combinations and design checks
    — Calculate and interpret prestress losses
    Professional Design Outcomes
    + Verify flexure, shear, deflection, and camber requirements
    + Interpret analysis results for engineering decision-making
    + Identify common modelling pitfalls and avoid design errors
    + Adopt professional bridge design workflows used in practice
    Webinar Focus
