## Description

This MCP server provides specialized tools for structural engineers to determine required rebar lap splice lengths. It accounts for material properties like concrete and steel strength, bar position (top bar vs. standard), and epoxy coatings. Use `calculate_lap_length` to find the required overlap, `validate_stagger_requirement` to ensure proper spacing between splices, and `check_cover_compliance` to verify concrete cover requirements. It also provides a `get_splice_summary` for quick reporting.

## Tools

### calculate_lap_length
Calculates the primary required lap splice length for a single rebar configuration

### check_cover_compliance
Verifies if the provided concrete cover is sufficient for the bar diameter

### get_splice_summary
Provides a human-readable summary of a calculated reinforcement configuration

### validate_stagger_requirement
Determines the minimum distance required between two consecutive splices

## Prompt Examples

**Prompt:** 
```
Calculate the lap length for a 20mm rebar with 30MPa concrete and 400MPa steel using Class B splice.
```

**Response:** 
```
The required lap length for this configuration is 1250 mm.
```

**Prompt:** 
```
Is a 40mm concrete cover enough for a 25mm epoxy-coated rebar?
```

**Response:** 
```
Yes, the concrete cover is sufficient for the effective diameter of the epoxy-coated bar.
```

**Prompt:** 
```
What is the minimum stagger distance for a 1000mm lap length if staggering is required?
```

**Response:** 
```
The minimum stagger distance required is 300 mm.
```

## Frequently Asked Questions

**How does bar position affect the calculation?**
Top bars require longer splices because concrete settlement can create a weak zone under the bar. The `calculate_lap_length` tool automatically adjusts for this.

**Does epoxy coating change the required length?**
Yes, epoxy coating reduces bond strength between steel and concrete, so the `calculate_lap_length` tool increases the required overlap to maintain structural integrity.

**How can I check if my concrete cover is sufficient?**
You can use the `check_cover_compliance` tool, which compares the bar diameter (including epoxy thickness) against your provided concrete cover.
