Unformatted text preview: SHEAR FORCE AND BENDING MOMENT
The internal bending moment is considered positive if it causes compression of the top fiber of the structural member under consideration as shown below. Negative other wise. Tension at Bottom Tension at top Positive Moment Negative Moment STEPS OF CONSTRUCTING SFD AND BMD
1. Draw FBD and solve for support reactions 2. Calculate the shear force along the member from left to right "Shear force due to distributed loading can be calculated as the area underneath the load. 3. Draw SFD b...
