Watch how a response spectrum analysis carries through to a Winkler soil-structure model in MIDAS GEN, without losing any seismic demand along the way.
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: 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.

MIDAS GEN — response spectrum and non-linear soil-structure analysis
Carrying seismic demand from a building model into a Winkler soil-foundation model without losing accuracy
Building superstructure, RC core wall, and foundation slab meshed together in one MIDAS GEN model, ready for response spectrum analysis.
Defining a code-based design spectrum function directly in MIDAS GEN, with full control over spectrum type, ground type, and behaviour factor.
Carrying the resulting seismic demand into a non-linear foundation model supported by Winkler soil springs.
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.
Set up and run a linear modal response spectrum analysis in MIDAS GEN, with foundations initially represented by idealised supports.
Transform response spectrum results into equivalent nodal forces and static load cases, while preserving the seismic demand from the dynamic analysis.
Replace idealised foundation restraints with Winkler soil springs and run a non-linear static analysis of the complete soil-foundation-structure system.
