Remark:
1. The exact calculation formulas for angle steel, I-beam and channel steel are very complicated, and the simplified formulas listed in the table are used to calculate approximate values.
2. F value: 3.34 for general models and those with a, 2.65 for those with b, and 2.26 for those with c.
3. e value: 3.26 for general models and those with a, 2.44 for those with b, and 2.24 for those with c.
4. The units of each length are millimeters (mm)
