Integrated Seismic Analysis of Buildings and Foundations in MIDAS GEN NX
Watch how a response spectrum analysis carries through to a Winkler soil-structure model in MIDAS GEN NX, without losing any seismic demand along the way.
Register Now →From building dynamics to soil-structure interaction, in one connected workflow
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.

MIDAS GEN NX — response spectrum and non-linear soil-structure analysis
FOCUS
Carrying seismic demand from a building model into a Winkler soil-foundation model without losing accuracy
2 Highlights From The Model
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.
What you'll take away
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.
Response spectrum analysis on a full building model
Set up and run a linear modal response spectrum analysis in MIDAS GEN NX, with foundations initially represented by idealised supports.
Converting dynamic results into static seismic loads
Transform response spectrum results into equivalent nodal forces and static load cases, while preserving the seismic demand from the dynamic analysis.
Introducing Winkler soil-structure interaction
Replace idealised foundation restraints with Winkler soil springs and run a non-linear static analysis of the complete soil-foundation-structure system.
