ABSTRACT
Shearing stresses due to bending occur in a structure when the bending moment changes. Thus, if the structure is subjected to a lateral shearing force, shearing stresses will occur as a result of this, and structural failure may occur, due to large shearing stresses. Moreover, in the case of beams with thin-walled cross-sections, such as channel and angle bars, the shearing stresses due to bending can cause the beam to twist. This is because the applied load of the laterally loaded beam is never placed through the structure's shear centre. This chapter shows the process to: understand shearing stresses due to bending, understand and calculate vertical shearing stresses, understand and calculate horizontal shearing stresses, understand and determine shear centre. It also shows the process to: understand and calculate shearing stress distribution in thin-walled beams, understand and calculate shear deflections, understand and calculate shearing stresses due to torsion.
