Column Construction Calculator

Column Construction Calculator contains 35 calculators to measure and calculate different column and civil engineering parameters.

NEW — Built-in Reference Library
Look up standard material properties and auto-fill them straight into any calculator:
• Steel — ASTM grades (A36, A992 W-shapes, A572 Grade 50, A500 Grade B & C HSS, A53 Grade B Pipe) with Yield Strength (Fy) and Modulus of Elasticity (E)
• Aluminum — common structural aluminum grades
• Concrete — ACI mix classes from 2500 psi to 10000 psi with compressive strength (f'c), modulus (Ec) and β₁ factor

Available in Metric (SI) and Imperial (USCS) Units
