Structural Analysis & FE Modelling
Understand the governing behaviour.
Investigate structural behaviour using mechanics, analytical models and finite element analysis, with explicit assumptions and validation.
The question
Start with the decision.
Which mechanism governs the behaviour of a member or connection?
How do material nonlinearity, restraints and contact affect the response?
Is a simplified model adequate, or is a more detailed FE representation needed?
The work
- Structural idealisation and analytical modelling.
- Nonlinear finite element modelling, including relevant material and geometric effects.
- Connection and member behaviour studies using Abaqus where appropriate.
- Sensitivity studies and comparison with suitable reference data.
- Interpretation of model response and its limits for the intended decision.
Deliverables
What you receive.
- An analysis note setting out geometry, loads, restraints and material assumptions.
- Model definitions and agreed numerical outputs.
- Interpreted response plots, governing mechanisms and sensitivity findings.
- A validation or comparison record with limitations stated.
Getting started
Information to define the scope
- The engineering question and required decision.
- Geometry, materials, loading and boundary-condition information.
- Relevant measured data, reference results and required deliverable format.
Relevant experience
Evidence for this scope.
Stainless-steel connections
Explain bolted joint response through mechanics and nonlinear FE.
Published researchColumn panel-zone capacity
Understand how column geometry and axial force influence joint shear capacity.
Published research / softwareCHS buckling under combined load
Repeat the same combined-load prediction for candidate CHS members.
Published connection research supports this analytical capability. It is collaborative research, not proof of a commercial design commission or universal validation for every connection. Any regulated design or certification scope must be established separately.
