2 Shear and Bending Moment Functions ± Will be DISCONTINUOUS where: { Distributed loads start or end { Concentrated forces act { Couple moments act ± Will be CONTINUOUS: { Within distributed loads { Between concentrated forces { Between couple moments ± FUNCTIONS ARE WRITTEN FOR CONTINUOUS ZONES BUT THEY ARE BASED ON THE COMPLETE FREE BODY DIAGRAM (UP TO THE CUT SECTION) Procedure for Shear and Moment Diagrams ± Determine support reactions ± Start at the LHS of the beam { Define regions where shear and moment diagrams will be continuous { Working Left to Right, section the beam within continuous zones and draw FBD of the whole beam up to that zone showing the exposed
