Define the Frame Column Analysis
1. Based on if a column section is a braced frame or unbraced frame.
2. Braced frame-indicates buckling mode shape does not involve translation of the end points
- A frame may not need actual cross bracing to be denoted as a 'braced frame'-could be braced by an intermediate wall. However, for simplicity assume if this information is not given, cross bracing would denote a braced frame.
3. Unbraced frame-a column that translates and rotates at a terminal end under axial compressive loads.
