## Description

This MCP server provides structural engineers and installers with the precise calculations needed for bolt pretensioning. It bridges the gap between design requirements and field execution by providing specific instructions for `calculate_minimum_pretension`, `determine_tightening_method`, `get_hardware_requirements`, and `validate_inspection_protocol`. Whether you are designing slip-critical connections or verifying torque-controlled installations, this tool ensures compliance with AISC and EN 1090 standards.

## Tools

### get_hardware_requirements
Identifies the necessary washers and surface treatments required for the bolt assembly

### validate_inspection_protocol
Defines how the installer should verify that the pretension has been correctly applied

### calculate_minimum_pretension
Determines the required axial tension force needed for the connection

### determine_tightening_method
Provides the specific tightening instruction (rotation or torque) to achieve the target tension

## Prompt Examples

**Prompt:** 
```
What is the minimum pretension for a 20mm bolt, grade 10.9, in a slip-critical connection requiring 50kN slip resistance?
```

**Response:** 
```
The minimum pretension required is 125.5 kN.
```

**Prompt:** 
```
What is the torque value for a 22mm, grade 8.8 bolt that is lightly oiled?
```

**Response:** 
```
The required torque value is 345 Nm.
```

**Prompt:** 
```
How should I inspect a turn-of-nut tightening for a grade 10.9 bolt?
```

**Response:** 
```
The inspection should be a visual angular measurement to ensure the specified rotation was achieved.
```

## Frequently Asked Questions

**Which standards does this tool support?**
The tool supports calculations based on AISC and EN 1090 standards.

**Can I use this for slip-critical connections?**
Yes, you can use `calculate_minimum_pretension` to determine the required tension for slip-critical connections.

**How do I know if I need hardened washers?**
You can use `get_hardware_requirements` to identify if hardened washers are necessary for your specific bolt diameter and connection type.
