FEM Analysis
Finite element analysis for complex loading, strengthening and modification - built on project-specific assumptions, existing-condition information and the proposed change.
Quick Answer
Finite element method (FEM) analysis models how a structure responds to loads, capturing behaviour that simple hand calculation cannot. It is used to assess existing structures, test proposed modifications and support strengthening design.
A model is only as good as its inputs. We document the assumptions, the existing-condition information used and the proposed change, so the results can be understood and challenged.

What Problems This Service Solves
Some questions cannot be answered reliably by simple calculation. Analysis helps, provided its assumptions are clear and grounded in the real structure.
Complex Load Paths
Irregular geometry, transfer structures and unusual loading may need a model to understand how forces are carried.
Proposed Modifications
Removing or adding structure changes how load flows. Analysis helps test whether the altered structure can perform as intended.
Uncertain Existing Capacity
Capacity depends on actual geometry, materials and condition. Models should reflect what investigation has found, not only the original drawings.
Strengthening Needs
Where capacity appears deficient, analysis helps identify the affected elements and check that a proposed scheme addresses them.
Questions of Adequacy
When opinions differ about structural adequacy, a documented model and its assumptions give everyone a common basis for discussion.
Design Efficiency
Informed analysis can help avoid unnecessarily conservative assumptions where the information supports it.

Frequently Asked
What is FEM analysis?
Finite element analysis is a computational technique that divides a structure into small elements to model how it responds to loads, capturing behaviour that hand calculation cannot.
When is FEM needed rather than hand calculation?
For irregular geometry, complex load paths, modification assessments or situations where the consequences of an error are significant. Simpler problems are often better served by simpler methods.
Can FEM assess my existing building?
Yes, when combined with reliable information about its geometry, materials and condition. Where that information is missing, investigation may be recommended first.
How reliable are the results?
They depend on the quality of the inputs. We state our assumptions and limitations clearly and, where useful, show how sensitive the results are to them.
Does FEM support strengthening design?
Yes. It can help identify where capacity is deficient and whether a proposed strengthening scheme is likely to achieve the required performance.
