Column Buckling Calculator

MechaniCalc Column Buckling Calculator compared with SkyCiv, RISA and Mathcad
MechaniCalc Column Buckling Calculator	SkyCiv	RISA	Mathcad
Method: The tool applies the Euler formula for long columns, the Johnson formula for intermediate columns and the secant formula for eccentric loads. The class of column is decided by comparing the slenderness ratio with a transition value.	Method: SkyCiv Section Builder gives finite strip method buckling loads for a cross section, used for Direct Strength Method design of cold-formed members. This is section-level stability, not an Euler column check.	Method: RISA-3D performs finite element analysis of members, plates and solids with P-Delta effects, and checks members against design codes. Buckling there is part of a whole-structure model.	Method: PTC Mathcad Prime is a worksheet for engineering calculations with solvers, units and plots. A column check is only available if the user writes the equations.
Inputs and outputs: Inputs are end condition (pinned-pinned, fixed-fixed, fixed-pinned, fixed-free), load, material, section, length and eccentricity. Outputs include critical force, critical stress, critical length, factors of safety, plots against length and a Word report.	Inputs and outputs: Inputs are the section geometry and material. Outputs are buckling factors and loads, along with section properties and stress contours.	Inputs and outputs: Inputs are a full structural model with members, supports and load cases. Outputs are member forces, deflections and code check results.	Inputs and outputs: Inputs and outputs are whatever the user defines, with live unit handling in SI, USCS and CGS.
Standards: No design code is named. The equations are textbook formulas, so results are not code-compliant design checks by themselves.	Standards: The finite strip results support AISI (2016) and AS 4600 (2018) for Direct Strength Method design.	Standards: Design is provided to AISC 360, Eurocode 3, CSA S16, AS 4100 and other codes for steel, plus concrete, aluminum, timber and masonry codes.	Standards: No built-in design code check for columns was found on the product page, the user sets the code equations.
Licence and cost: Free use is limited, with predefined materials and sections, no login and no reports. Individual plans are paid subscriptions, billed monthly or yearly.	Licence and cost: Browser-based with a free sign-up, plans without lock-in contracts. Price is not shown on the pages consulted.	Licence and cost: Commercial licence, Windows only (64-bit Windows 8.1, 10, 11).	Licence and cost: Commercial licence through the PTC Store, with a 30-day trial. Windows 11 64-bit is required.
When to choose it: Choose it for a single column with defined ends and a known load, when you need a stated critical load and a safety factor in minutes.	When to choose it: Choose it for thin-walled cold-formed sections where local and distortional buckling matter.	When to choose it: Choose it when the column is one element of a frame that needs code design.	When to choose it: Choose it when you want a documented, reusable calculation sheet with your own formulas and unit checks.
