Aluminium Curtain Wall Profile Moment of Inertia Determining Calculator

Curtain wall profile moment of inertia

Vertical Mullion [ Wind Load ]

Design wind load (kg/m²):

Wind Speed (km/h)

Module Width (cm): { G }

Span (cm): { L }

Allowable Deflection (cm): { f }

Required Moment of Inertia: { Ix } (cm⁴)

Horizontal Transom [ Dead Load ]

Outer glass thickness (mm):

Inner glass thickness (mm)*:

Req. Moment of Inertia (dead load): { Iy } (cm⁴)

Req. Moment of Inertia (wind load): { Ix } (cm⁴)

* Enter "0" for single glazing.
** For triple glazing, enter the sum of the center and inner glass thicknesses.

About Profile Deflection

This calculator is used for calculating the required Moment of Inertia for Aluminium Profiles. The calculation model is based on simply supported single span beams under trapezoidal load.

Please contact FMT for other support or load types. This calculator is for preliminary design purposes only. FMT Engineering Inc. does not accept any responsibility for the calculations and results. The design shall be verified by a professional structural engineer.
