Beams are the structural members that support transverse loads on them and are subjected to flexure and shear. An I shape is a common cross section for a steel beam where the material in the flanges at the top and bottom is most effective in resisting bending moment and the web provides for most of the shear resistance. As discussed in the “Design of Beams” section of Chapter 7-context of wood beams-the design process involves selection of a beam section on the basis of the maximum bending moment to be resisted. The selection is, then, checked for shear capacity. In addition, the serviceability requirement imposes the deflection criteria for which the selected section should be checked.
