## Description

This MCP server provides structural engineering tools to manage concrete durability. It allows agents to calculate the maximum allowable bar spacing using `calculate_max_bar_spacing`, determine the necessary reinforcement ratio with `calculate_reinforcement_ratio`, and predict crack widths via `estimate_crack_width`. By accounting for exposure classes like MARINE_SEA_SPRAY or DEICING_SALTS, it ensures reinforcement designs meet strict durability requirements.

## Tools

### estimate_crack_width
Predicts the actual width of a crack produced by a specific reinforcement configuration

### get_exposure_constraints
Retrieves the standard crack width limits and safety factors associated with a specific environmental exposure class

### calculate_max_bar_spacing
Determines the largest possible distance between reinforcement bars to satisfy a specific crack width constraint

### calculate_reinforcement_ratio
Calculates the minimum percentage of steel area required relative to the concrete area to prevent exceeding crack limits

## Prompt Examples

**Prompt:** 
```
What is the maximum bar spacing for a 20mm bar with 30mm cover and 250MPa stress in a marine environment with a 0.3mm crack limit?
```

**Response:** 
```
The maximum allowable bar spacing for this configuration is 185.5 mm.
```

**Prompt:** 
```
Calculate the reinforcement ratio for 15mm bars, 40mm cover, 300MPa stress, and a 0.2mm crack limit in a de-icing salt environment.
```

**Response:** 
```
The required reinforcement ratio is 0.0125.
```

**Prompt:** 
```
Estimate the crack width for 12mm bars spaced at 150mm with 35mm cover and 280MPa stress in an urban dry environment.
```

**Response:** 
```
The estimated crack width is 0.14 mm.
```

## Frequently Asked Questions

**How do I find the maximum distance between bars?**
Use the `calculate_max_bar_spacing` tool. You will need to provide the concrete cover, bar diameter, steel stress, crack width limit, and the exposure class.

**Can I predict the crack width for a specific setup?**
Yes, the `estimate_crack_width` tool calculates the expected width based on your bar spacing, diameter, and environmental exposure.

**What exposure classes are supported?**
Supported classes include URBAN_DRY, DEICING_SALTS, MARINE_SEA_SPRAY, and FREEZING_THAWING.
