TABLE OF CONTENTS All notation will be specifically defined where it is first introduced. The following Table will serve as a reference and guide. In general, capital letters will be used for properly dimensioned physical quantities, and the corresponding lower-case letters will stand for the same quantities expressed in dimensionless form. Where more than one meaning has been assigned to a symbol, the correct use will be obvious from the context. As far as possible, subscripts will have consistent values; representative samples are given in the Table.
| A | = area |
| B, D | = width and depth of a cross section |
| C mx, C my | = equivalent moment factors used in AISC Specification |
| E, E t | = Young's modulus, tangent modulus |
| e | = end eccentricity |
| | = concrete compressive strength |
| G | = elastic shear modulus |
| I | = moment of inertia |
| K | = ? ?a 2 dA where a is defined as the distance from a point on the cross section to the shear center |
| K T | = St. Venant torsion constant |
| L | = member length |
| 1 | = segment length |
| M | = bending moment |
| M ? | = bimoment or warping moment |
| M pcx, M pcy | = fully plastic moments of section about the x- and y-axis, respectively, reduced for the presence of axial load when P ? 0 |
| M px, M py | = fully plastic moments of section about the x- and y-axis, respectively, when P = 0 |
| M ucx, M |
