## Description

This MCP server provides structural engineering tools to design concrete columns subjected to biaxial bending. It uses the interaction diagram method to determine if a section is safe under combined axial loads and moments (Mx and My). Users can `analyze_section_capacity` to check safety ratios, `calculate_required_reinforcement` to find the minimum steel area, `generate_reinforcement_layout` for physical bar arrangements, and `check_slenderness_effects` to account for second-order moments in slender columns.

## Tools

### calculate_required_reinforcement
Finds the minimum area of steel needed to satisfy the load combination

### check_slenderness_effects
Evaluates if the column is "short" or "slender" and calculates the moment magnification factor

### generate_reinforcement_layout
Provides a physical arrangement of steel bars for the calculated required area

### analyze_section_capacity
Determines if the current column dimensions and material strengths can support the applied loads

## Prompt Examples

**Prompt:** 
```
Check if a 300x300mm column with 30MPa concrete and 500MPa steel is safe under 1000kN axial load and 50kNm moments in both directions.
```

**Response:** 
```
The capacity ratio for this column is 0.72, which means the section is safe.
```

**Prompt:** 
```
How much steel area do I need for a 400x400mm column with 1500kN axial load and 80kNm moments?
```

**Response:** 
```
The required steel area is 1250 mm² with a reinforcement ratio of 0.0078.
```

**Prompt:** 
```
Generate a layout for 1500mm² of steel in a 350x350mm column with 40mm cover.
```

**Response:** 
```
The layout consists of 6 bars with a spacing of 120mm in both directions.
```

## Frequently Asked Questions

**How do I check if my column is safe?**
Use the `analyze_section_capacity` tool. It will return a capacity ratio; if the ratio is 1.0 or less, the column is safe.

**Does this tool account for slenderness?**
Yes, you can use `check_slenderness_effects` to calculate the moment magnification factor for slender columns.

**Can I get a physical layout for the steel bars?**
Yes, once you have the required steel area, use `generate_reinforcement_layout` to get the bar count and spacing.
