Pipe Column Capacity Calculator
Axial capacity of a steel pipe prop/column — site props, shoring, stub columns.
An 88.9×4 pipe at 3 m carries ~10–11 tonnes design — close to what adjustable steel props claim at full extension. Eccentric loading (always, on site) halves it; hence prop ratings.
Formula
Pipe Column Capacity Calculator is a free pipe column capacity for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Pipe Column Capacity Calculator
Axial capacity of a steel pipe prop/column — site props, shoring, stub columns. The calculation implements Buckling curve a (hollow sections), γ = 1.5 (IS 800 buckling curve a; IS 4014 props). An 88.9×4 pipe at 3 m carries ~10–11 tonnes design — close to what adjustable steel props claim at full extension. Eccentric loading (always, on site) halves it; hence prop ratings.

Frequently asked questions
What formula does the Pipe Column Capacity Calculator use?+
It computes Buckling curve a (hollow sections), γ = 1.5, per IS 800 buckling curve a; IS 4014 props. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
An 88.9×4 pipe at 3 m carries ~10–11 tonnes design — close to what adjustable steel props claim at full extension. Eccentric loading (always, on site) halves it; hence prop ratings.
Can I use this for real structural design?+
It implements the exact textbook/code formula cited below the result and is ideal for sizing, checking and learning. Final designs should be verified by a qualified engineer against the full code with all load cases.
Is the Pipe Column Capacity Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
