# Section Property Calculator Skill ## Purpose The Section Property Calculator Skill calculates cross-sectional properties for structural sections including area, moment of inertia, section modulus, and plastic modulus for both standard and custom shapes. ## Capabilities - Calculate cross-sectional properties (A, I, S, Z, r) - Support for standard shapes (W, HSS, C, L, pipe) - Custom section analysis - Composite section properties - Cracked section analysis for concrete - Plastic section modulus calculation - Effective section properties - Built-up section analysis ## Usage Guidelines ### When to Use - Determining section properties for design - Analyzing composite sections - Evaluating cracked concrete sections - Designing built-up members ### Prerequisites - Section geometry defined - Material properties specified - Cracking criteria established (for concrete) - Effective width defined (for composites) ### Best Practices - Use correct axis orientation - Account for holes and penetrations - Consider effective sections per code - Verify against published values ## Process Integration This skill integrates with: - Reinforced Concrete Design - Structural Steel Design - Bridge Design LRFD ## Configuration ```yaml section-property-calculator: standard-shapes: - W-shapes - HSS-rectangular - HSS-round - channels - angles - pipes analysis-types: - gross - net - effective - cracked ``` ## Output Artifacts - Section property ta...
