    AI Summary

    By the end of this live session, you'll understand how to take a building
    from response spectrum analysis through to a verified, non-linear soil-structure model in MIDAS GEN NX.

     

    1. Response spectrum analysis on a full building model

    2. Converting dynamic results into static seismic loads

    3. Introducing Winkler soil-structure interaction

    Description

    Modelling a building and its foundation as a single structural system gives a more realistic picture of seismic behaviour, but it means carefully bridging structural dynamic analysis with soil-structure interaction, especially once the soil starts behaving non-linearly.

     

    This session presents a complete workflow in MIDAS GEN NX: a linear modal response spectrum analysis of a building on idealised pinned supports, converted into equivalent static seismic actions, then transferred into a foundation model supported by Winkler soil springs for a full non-linear assessment.

    Key Points

    Single Connected Model: Building superstructure, RC core wall, and foundation slab meshed together in one MIDAS GEN NX model, ready for response spectrum analysis.

    NTC2018 Response Spectrum Setup: Defining a code-based design spectrum function directly in MIDAS GEN NX, with full control over spectrum type, ground type, and behaviour factor.

    Winkler Soil-Spring Foundation: Carrying the resulting seismic demand into a non-linear foundation model supported by Winkler soil springs.
