www.SSMA.com6 Copyright © 2022 by the SSMA Gross Properties Ix: Moment of inertia of the cross section about the x-axis. Sx: Section modulus about the x-axis. R x: Radius of gyration of cross section about the x-axis. Iy: Moment of inertia of cross section about the y-axis. Ry: Radius of gyration of cross section about the y-axis. Effective Properties Ixe: Effective moment of inertia about the x-axis. Sxe: Effective section modulus about the x-axis. Mal: Allowable moment based on local buckling. Mad: Allowable moment based on distortional buckling, assuming Kφ = 0. Ma: Allowable moment for track and channel members, based on local buckling only. Vag: Allowable strong axis shear away from punchout, calculated in accordance with AISI S100 Section C3.2.1. Vanet: Allowable strong axis shear at the punchout, calculated in accordance with AISI S100 Section C3.2.2. Torsional and Other Properties J: St. Venant torsional constant. The numbers shown in the tables for J have been multiplied by 1,000. The actual values can be obtained by dividing the listed numbers by 1,000. Cw: Torsional warping constant. Xo: Distance from the shear center to the centroid along the principal x-axis. m: Distance from shear center to mid-plane of web. Ro: Polar radius of gyration of cross section about the shear center. β: 1- (Xo/Ro)2 L u: Critical unbraced length for lateral-torsional buckling. Members are considered fully braced when unbraced length is less than Lu. Kφ Distortional buckling moment (Mad) is calculated without the beneficial effect of sheathing to rotational stiffness. Kφ = 0. X X Y Definitions of Structural Property Symbols Web Depth (h) to Thickness (t) Ratios 2,3,4 1h/t exceeds 200 2h value used for h/t calculation is the flat width of the web. For S members, this is the out-to-out member size, minus twice the thickness, minus twice the inside bend radius. 3h/t values exceeding 260 are marked with a dash ( - ). 4h/t values in this table apply to S (studs and joists) members only and do not apply to tracks and channels.
