# Midas Civil Special Load and Design Utilities
|
|
|
|
## Definition
|
|
|
|
Midas Civil special load and design utilities are the analysis-reference workflows that sit around the core FE solve: support-settlement combinations, before/after composite-section analysis, unknown-load optimization, arbitrary-shape column design, and wave-load generation.
|
|
|
|
## How It Works
|
|
|
|
Support settlement auto-consideration generates settlement cases or combinations. Steel composite section before/after composite analysis changes section stiffness as composite action develops. Unknown load solution uses optimization to identify loads that satisfy target responses. Arbitrary-shape column design includes moment magnification, long-column effects, braced/unbraced classification, 3D P-M interaction, and shear design. Wave load generation includes offshore member wave forces and wave theories such as Airy, Stokes, stream function, cnoidal, and solitary waves.
|
|
|
|
## Solver Development Notes
|
|
|
|
- Some production features are model generators or postprocessors rather than new FE equations.
|
|
- Optimization-based load identification needs a clear objective, constraints, design variables, and verification against the recovered target response.
|
|
- Design utilities require traceable mapping from FE force output to code-check quantities.
|
|
- Wave and settlement generators should be tested at the load-vector/envelope level before full-structure tests.
|
|
