## Description

This MCP server provides specialized engineering tools to evaluate the shear transfer capacity of concrete interfaces. It allows users to determine the maximum shear force an interface can resist based on reinforcement area, concrete compressive strength, and joint conditions. Using `calculate_shear_capacity`, engineers can model both monolithic pours and cold joints while accounting for surface roughness. The server also includes `evaluate_safety_factor` to verify design compliance and `determine_required_reinforcement` to solve for the necessary steel area to meet specific shear demands.

## Tools

### compare_interface_conditions
Evaluates how much capacity is lost when transitioning from a monolithic pour to a cold joint

### determine_required_reinforcement
Calculates the minimum steel area required to resist a specific shear load

### calculate_shear_capacity
Determines the maximum shear force the interface can resist

### evaluate_safety_factor
Checks if the current design is safe against a specific applied load

## Prompt Examples

**Prompt:** 
```
What is the shear capacity for an interface with 500mm² reinforcement, 30MPa concrete, and a 1.2 roughness factor in a monolithic condition?
```

**Response:** 
```
The calculated shear capacity is 150.0 kN.
```

**Prompt:** 
```
Is a design safe if the applied shear is 80kN and the calculated capacity is 100kN?
```

**Response:** 
```
Yes, the safety factor is 1.25, which is greater than 1.0.
```

**Prompt:** 
```
How much reinforcement is needed for a 200kN shear load on a 1000mm² area with 25MPa concrete (monolithic, roughness 1.0)?
```

**Response:** 
```
The required reinforcement area is 266.67 mm².
```

## Frequently Asked Questions

**How does the tool handle monolithic vs cold joint conditions?**
The `calculate_shear_capacity` tool uses a boolean flag to distinguish between a continuous monolithic pour and a separate cold joint, adjusting the capacity based on the expected aggregate interlock and cohesion.

**Can I calculate the required steel area for a specific load?**
Yes, you can use the `determine_required_reinforcement` tool to find the minimum reinforcement area (mm²) needed to resist a target shear force.

**What is the purpose of the roughness factor?**
The roughness factor is a coefficient used in `calculate_shear_capacity` to represent the surface texture, which influences the aggregate interlock and overall shear resistance.
