The detailed process for drawing shear force and bending moment diagram
Shear force and bending moment are considered as the primary factors in designing members. Therefore, there should be clear conception on how to draw these SFD and BMD.
Specific parameters are required for each design process to design the capacity of members. These parameters function as input in design process and finally you obtain cross-sectional and material properties.
This video sheds light on graphical approach to demonstrates the detailed process for analyzing a simply supported beam and shear force and how to draw a bending moment diagram. Conventions are identical as that of applied in softwares like etabs and sap2000.
Bending Moment is positive downward so as to clarify efficiently for positioning reinforcement.
This video will demonstrate the steps to measure SFD & BMD.
