V- and M- Diagrams for Frames
Procedures:
1. Determine reactions at the frame supports
2. Method of Sections determine axial force, shear force, and bending moment at the ends of each member.
3. Free-Body Diagram with all load components acting parallel and perpendicular to the members axis.
4. M(+) on the compression side and M(-) on the tension side.

THE METHOD OF SUPERPOSITION(for M-Diagram)
- Treating each load case separately.
- M-Diagram is divided into series of parts and then combined the results.
- Useful for a structural member under a complicated shape of loadings.
- Advantageous for statically indeterminate beams.
