Column Design Calculator

Design columns with P-M interaction and slenderness analysis

ACI 318-19DPT 1008-61Slenderness & Capacity Ratio

Calculation results are decision-support tools. The design engineer must review and verify all results independently.

Unit System

Height (m)

Width (mm)

Depth (mm)

Major axis Lu (m)

Usually equal to beam-to-beam height

Minor axis Lu (m)

Use factored values (e.g. 1.2D+1.6L) in kN / kN·m; convert service loads to factored first

Axial load (kN)

Moment X (kN·m)

Moment Y (kN·m)

Load components (D/L/W/E) — enables project load-combo envelopes

Service-level actions. Complete every row you start; leave an optional row blank when that category does not exist.
