Appendix A — Geometric Properties of Standard Beams

A.1 Wide-Flange (W) Shapes. US Customary Units

Cross-sectional geometry of an I shaped beam with labeled dimensions: an overall height labeled d, a flange width labeled b sub f, a flange thickness labeled t sub f, and a web thickness labeled t sub w. A gray dotted line representing the x-axis passes horizontally through the middle of the beam, and another gray dotted line representing the y-axis passes vertically through the center of the web. The section is symmetric about both the x and y axes.

A.2 Wide-Flange (W) Shapes. SI Units

A.3 WT Shapes. US Customary Units

Cross-sectional geometry of a T-shaped beam with labeled dimensions: an overall height labeled d, a flange width labeled b sub f, a flange thickness labeled t sub f, and a web thickness labeled t sub w. A gray dotted line representing the x-axis passes horizontally through the centroid of the beam, with the distance from the top of the flange to the x-axis labeled y bar. Another gray dotted line representing the y-axis passes vertically through the center of the web. The section is symmetric about the y-axis.

A.4 WT Shapes. SI Units
