Member selection using standard beam sections

Find a section that satisifies all criteria:

• Strength:

  • Bending stress

  • Shear stress

• Stiffness:

  • Deflections at service loads

Note: There are many other possible criteria to check, such as floor vibrations, stresses at end connections, and so on. We will used a simplified procedure that is adequate for many cases and illustrates how member design criteria fit into the design process.
