## Description

This MCP server provides specialized engineering tools to calculate the reduction in prestress force in concrete structures. It accounts for both instantaneous losses--such as elastic deformation, anchorage slip, and friction--and time-dependent losses, including concrete creep, shrinkage, and steel relaxation. Engineers can use `calculate_total_prestress_loss` for a complete assessment or `get_loss_sensitivity_analysis` to understand how changes in concrete age or strength impact the final results.

## Tools

### calculate_instantaneous_losses
Determines the immediate losses that occur during the tensioning and anchoring process

### calculate_time_dependent_losses
Estimates the losses that accumulate over time due to material properties

### calculate_total_prestress_loss
Provides a single comprehensive calculation of all losses (instantaneous and time-dependent)

### get_loss_sensitivity_analysis
Answers how much the total loss changes when a specific variable is adjusted

## Prompt Examples

**Prompt:** 
```
Calculate the total prestress loss for an initial prestress of 150 MPa, concrete age of 28 days, concrete strength of 40 MPa, and low-relaxation tendon.
```

**Response:** 
```
The total loss is 18.45 MPa, leaving a remaining prestress of 131.55 MPa.
```

**Prompt:** 
```
What are the immediate losses for 140 MPa initial prestress and 35 MPa concrete strength?
```

**Response:** 
```
The total instantaneous loss is 12.3 MPa.
```

**Prompt:** 
```
How much does the total loss change if I increase the concrete strength by 10%?
```

**Response:** 
```
Increasing the concrete strength by 10% results in a 2.1% decrease in total loss.
```

## Frequently Asked Questions

**What types of losses are calculated?**
The tool calculates elastic loss, anchorage slip loss, friction loss, creep loss, shrinkage loss, and relaxation loss.

**Can I perform sensitivity analysis?**
Yes, you can use `get_loss_sensitivity_analysis` to see how adjusting parameters like concrete age or strength affects the total loss.

**What inputs are required for a total loss calculation?**
You need the initial prestress, concrete age, concrete strength, and the tendon relaxation class.
