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.

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.
