1. Beam loads are given in total uniform load (W Lbs) not uniform load (w lbs/ft or w lbs/in). 2. Beam loads are based on a simple span and assumed to be adequately laterally braced. Unbraced spans can reduce beam load carrying capacity. 3. Deduct channel weight from the beam loads. 4. For concentrated midspan point loads, multiply beam loads by 50% and the corresponding deflection by 80%. 5. All beam loads are for bending about Axis 1-1.
