## Description

This MCP server provides structural engineering tools to design reinforced concrete members subjected to torsional loads. It follows ACI provisions to manage the interaction between shear and torsion. Users can determine required reinforcement using `calculate_torsion_reinforcement`, evaluate remaining shear capacity with `evaluate_shear_capacity`, identify torsion types via `check_torsion_type`, and verify section adequacy with `validate_section_geometry` to prevent web crushing.

## Tools

### calculate_torsion_reinforcement
Determines the required amount of closed stirrups and longitudinal steel for a given torsional load

### check_torsion_type
Analyzes if the provided loading scenario qualifies as equilibrium or compatibility torsion

### evaluate_shear_capacity
Calculates the remaining shear capacity of a member after accounting for the presence of torsion

### validate_section_geometry
Verifies if the concrete section dimensions are sufficient to prevent web crushing under the specified torsion and shear

## Prompt Examples

**Prompt:** 
```
Calculate the reinforcement needed for a 300x500mm section with 10 kNm torsion and 50 kN shear (concrete 30 MPa, steel 400 MPa, equilibrium).
```

**Response:** 
```
The required stirrup area is 125 mm² and the total longitudinal steel area is 210 mm².
```

**Prompt:** 
```
Is a 200x200mm section adequate for 15 kNm torsion and 40 kN shear with 25 MPa concrete?
```

**Response:** 
```
No, the section geometry is inadequate and exceeds the crushing threshold.
```

**Prompt:** 
```
What is the remaining shear capacity for a 400x400mm section with 5 kNm torsion and 100 kN shear?
```

**Response:** 
```
The available shear capacity is 145 kN with a utilization ratio of 0.68.
```

## Frequently Asked Questions

**How does this tool handle equilibrium vs compatibility torsion?**
The `check_torsion_type` tool identifies the category. If the system is statically determinate, it is treated as Equilibrium torsion, requiring full reinforcement resistance.

**Can I check if my concrete section is large enough?**
Yes, use `validate_section_geometry` to verify if the section dimensions prevent web crushing under the specified torsion and shear loads.

**Does it account for combined shear and torsion effects?**
Yes, `evaluate_shear_capacity` applies ACI interaction equations to calculate the remaining shear capacity after accounting for torsional stress.
