This MCP server provides specialized tools for structural engineering reinforcement calculations. It allows AI agents to determine the exact quantity of longitudinal reinforcement and transverse stirrups for elements like beams, columns, and slabs. By using estimate_total_project_rebar, you can obtain a complete summary of total weight and length, accounting for concrete cover, lap lengths, and waste factors.

4 tools expose this connector's capabilities to your AI agent.

calculate_longitudinal_reinforcement

Calculates the quantity of primary bars running the length of the element

calculate_transverse_reinforcement

Calculates the quantity of stirrups or ties for the element

estimate_total_project_rebar

Provides a high-level summary of all reinforcement for a single structural element

get_element_type_details

Provides the standard reinforcement characteristics for a specific element type

Estimate the total rebar needed for a beam that is 5m long, 0.3m wide, and 0.5m high. Use 16mm longitudinal bars at 15cm spacing and 8mm stirrups at 20cm spacing, with 30mm concrete cover.

The total estimated rebar weight for the beam is 142.5 kg, with a total length of 32.4 meters.

How many longitudinal bars are needed for a 4m long column, 0.4m wide and 0.4m deep, using 20mm bars spaced at 10cm with 40mm cover?

You will need 4 longitudinal bars for this column.

What are the standard reinforcement characteristics for a slab?

For a slab, the standard lap factor is 1.2 and the standard stirrup spacing factor is 0.0.

The server supports standard elements including beams, columns, slabs, and footings via the `get_element_type_details` tool.
