a5c-ai 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
