Predict concrete shrinkage strain, physical deformation, and optimal joint spacing using the ACI 209 model.

4 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides structural engineering tools to predict concrete shrinkage behavior. It uses the ACI 209 model to calculate shrinkage strain based on environmental factors like humidity and material properties like cement and aggregate types. Engineers can use get_shrinkage_strain to find the strain value, get_deformation_mm to calculate physical length changes, and get_recommended_joint_spacing to determine the best distance between control joints to prevent cracking. It also includes get_material_properties for looking up specific shrinkage coefficients.

Calculate the shrinkage strain for concrete that is 28 days old, in 50% humidity, with a thickness of 200mm, using Standard cement and Fine aggregate.

The predicted shrinkage strain is 0.00045.

What is the recommended joint spacing for a concrete member with a shrinkage strain of 0.0005, a thickness of 150mm, and a compressive strength of 30 MPa?

The maximum recommended joint spacing is 3500 mm, with a Low risk level.

How much will a 5000mm long concrete beam deform if the shrinkage strain is 0.0004 and the restraint factor is 0.3?

The total deformation is 2.0 mm, and the restrained deformation is 1.4 mm.

The server uses the ACI 209 shrinkage prediction model to calculate strain and deformation.
