    Description

    This technical webinar demonstrates the practical application of CS454 bridge assessment through real UK project case studies, presented by Abinash Acharya, Technical Lead Bridge Engineer at WSP.

    The session explains how CS454 and associated DMRB standards are applied to two representative bridge assessment projects and how these requirements are efficiently implemented in MIDAS CIVIL NX:

    • A multi-span post-tensioned concrete bridge assessed in accordance with CS 454 and CS 455

    • A steel–concrete composite bridge assessed in accordance with CS454, CS455, CS456 and CS457

     

    Key technical challenges — such as geometric complexity, modelling strategy, construction sequence effects, and assessment-driven decision-making — are discussed in the context of real engineering practice.

     

    Key CIVIL NX Features Covered

    • CS454 compliant moving load analysis and vehicle load modelling

    • Construction stage analysis for post-tensioned and composite bridges

    • Efficient handling of complex bridge geometry and multi-span systems

    • Assessment-oriented load combinations and result interpretation

    • Automated Excel report generation directly from analysis results

    • End-to-end workflow from assessment modelling to final reporting

    3 Takeaways for Attendees

    Apply CS454 moving load assessment procedures within MIDAS CIVIL NX, aligned with current UK assessment practice.

    Develop robust assessment models for multi-span post-tensioned and steel–concrete composite bridges, accounting for geometric complexity and construction sequence effects.

    Translate analysis results into structured, CS454 compliant assessment reports, supporting efficient decision-making for re-rating, strengthening, and asset management.
