  1. TOTAL STATIC LOAD in LBS.
  2. Upper line is MAXIMUM ALLOWABLE UNIFORM LOAD creating 25,000 PSI Bending Stress about the X-Axis based on SIMPLE BEAM condition.
  3. Lower line shows TOTAL UNIFORM LOAD which produces a defl ection of 1/240th of the SPAN, (i.e.; 1/2" Def. for 120" Span)
  4. Multiply values in upper line by 0.5 to obtain ALLOWABLE CENTER CONCENTRATED LOAD at 25,000 PSI Stress. Defl ection by 0.8.
  5. Load limited by spot weld shear.
  6. For punched channel, reduce weld limited loads by 0.75 due to 4" weld spacing.
  7. *** Load controlled by 25,000 PSI design stress.

  1. COLUMN LOADS are allowable axial loads applied at the section centroid. Loads applied at the slot face must be reduced for Eccentricity.
  2. ALLOWABLE COLUMN LOADS shown are based upon an effective length factor K = 0.8 standard engineering practice required for evaluation of other conditions.
