Free Online Base Plate Calculator

The SkyCiv Base Plate Calculator simplifies the design and verification of steel column-to-base plate connections while also checking anchorage to concrete support. It’s a valuable tool for structural engineers, designers,
and engineering students who need fast, accurate calculations. A downloadable PDF report is available with the paid subscription.

Designed by structural engineers for structural engineers, this calculator complies with industry design codes, including AISC 360, EN 1992-1-1, EN 1993-1-8, AS 4100, CSA S16, and NSCP 2015 for base plate design. Anchorage calculations follow ACI 318-19, EN 1992-4, AS 5216, CSA A23.3, and NSCP 2015. With fully referenced equations, users can confidently ensure their designs meet the latest standards.

A well-designed base plate is only as strong as its anchorage. This tool checks anchor quantity, layout, and size, helping engineers confirm structural adequacy. Whether designing a single anchor or a group, the calculator classifies and evaluates each case accordingly. It also provides graphical representations of concrete failure modes, offering valuable insight into potential weak points.

Manually checking dimensions can be time-consuming. This calculator ensures compliance and constructibility by verifying clearances, required minimum and maximum dimensions, edge distances, spacing, and concrete cover. It also detects design clashes, overlaps, and minor details that might be easily overlooked.

With full access, users can generate comprehensive reports in PDF or HTML format. Each report presents calculations clearly, with step-by-step breakdowns and references to the selected design code. Engineers can review every detail with confidence—no black boxes, no missing information.
