# Load Combination Generator Skill

## Purpose

The Load Combination Generator Skill creates load combinations for structural design per ASCE 7, AASHTO LRFD, and other applicable codes for both ASD and LRFD design methods.

## Capabilities

- Generate ASCE 7 load combinations (ASD and LRFD)
- Generate AASHTO LRFD load combinations
- Support for special load combinations (seismic, wind)
- Custom load factor specification
- Load case matrix generation
- Strength and serviceability combinations
- Fatigue load combinations
- Multiple load path considerations

## Usage Guidelines

### When to Use
- Developing structural design loads
- Creating analysis load cases
- Checking code compliance
- Evaluating critical load patterns

### Prerequisites
- Load types identified
- Risk category determined
- Design method selected
- Applicable codes identified

### Best Practices
- Include all applicable load types
- Consider load direction effects
- Document any special combinations
- Verify combination applicability

## Process Integration

This skill integrates with:
- Structural Load Analysis
- Reinforced Concrete Design
- Structural Steel Design
- Bridge Design LRFD
