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.

Connections

• Midas Civil Moving Load Bridge Analysis is another load-generation workflow.
• Midas Civil PSC and Prestress Loss Analysis shares staged section and bridge-design concerns.
• Abaqus Structural Optimization and Parametric Studies gives a broad optimization comparison point.
