A useful video tutorial on drawing Shear Force and Bending Moment Diagram
This construction article briefly demonstrates how to draw SFD and BMD. SFD stands for Shear Force Diagram and BMD stands for Bending Moment Diagram. These two play a major role for creating the design of members.
Specific parameters are necessary for each design method to design the capacity of members. These parameters act as input in design process and as an end result there will be cross-sectional and material properties.
This video focuses on graphical approach to demonstrate how analysis of a simply supported beam is prepared and drawing is made for shear force and Bending moment diagram. Conventions are similar to that applied in software like etabs and sap2000. Bending Moment is positive downward with the purpose of clarifying in superior manner where reinforcement should be positioned.
