## Description

This MCP server provides specialized engineering tools for post-tensioning design in concrete slabs using the Load Balancing Method. It allows AI agents to perform complex structural calculations, including determining the `calculate_jacking_force` to account for friction and anchorage losses, calculating `determine_tendon_geometry` for spacing and area, predicting `calculate_elongation` for field verification, and performing `verify_design_safety` to ensure compatibility with concrete strength.

## Tools

### calculate_elongation
Predicts the physical stretch of the tendon to allow for field verification

### verify_design_safety
Validates if the calculated post-tensioning requirements are compatible with the concrete strength

### calculate_jacking_force
Determines the total initial force required to overcome losses and achieve the target balancing force

### determine_tendon_geometry
Calculates the physical dimensions and placement of the tendons within the slab

## Prompt Examples

**Prompt:** 
```
Calculate the jacking force for a 10m span slab, 250mm thick, with 15 kN/m² load and 30 MPa concrete using a parabolic profile.
```

**Response:** 
```
The required jacking force is 450.5 kN with an effective force of 425.2 kN after accounting for losses.
```

**Prompt:** 
```
What is the expected elongation for a tendon with 500 kN jacking force, 150 mm² area, and 12m length with a modulus of 200000 MPa?
```

**Response:** 
```
The predicted elongation for the tendon is 45.0 mm.
```

**Prompt:** 
```
Check if a design with 35 MPa concrete, 400 kN jacking force, and 200mm slab thickness is safe.
```

**Response:** 
```
The design is safe with a reserve capacity of 12.5 MPa.
```

## Frequently Asked Questions

**What is the Load Balancing Method used here?**
It is a design approach where the tendon profile is shaped to create upward pressure that offsets a portion of the downward gravity loads.

**How does the tool handle friction losses?**
The `calculate_jacking_force` tool includes an optional parameter to account for the friction coefficient between the tendon and the duct.

**Can I verify if my design is safe?**
Yes, you can use the `verify_design_safety` tool to check if the induced compressive stresses are within the limits of your concrete strength.
