COLUMN LOADING
Based on simple beam condition using an allowable design stress of 25,000 psi (172 MPa) in accordance with MFMA, with adequate lateral
bracing (see page 11 for further explanation). Actual yield point of cold rolled steel is 42,000 psi. To determine concentrated load capacity at
mid span, multiply uniform load by 0.5 and corresponding deflection by 0.8. *Failure determined by weld shear.
Reference page 14 for general fitting and standard finish specifications.
