W Steel Beam Uniform Load

Overview

Engineering reference data for W Steel Beam Uniform Load in building construction.

Key Formulas

U-value

$U = \frac{1}{R_{total}}$

Overall heat transfer coefficient.

Heat Loss

$Q = U A \Delta T$

Heat transfer through building envelope.

Variables

Symbol	Description	Unit
$U$	U-value	W/(m²·K)
$A$	Area	m²
$\Delta T$	Temperature difference	K

Data Table

Units Conversion

• 1 inch (in) = 25.4 mm
• 1 foot (ft) = 0.3048 m
• 1 pound-force (lbf) = 4.44822 N

Note: The allowable loads in the table are based on conservative ASD (Allowable Stress Design) calculations for steel with a yield strength of 36 ksi. Higher strength steel (e.g., 50 ksi) and the LRFD (Load and Resistance Factor Design) method are also common in practice.
