Channel Loading
The multipliers shown in the beam loading conversion table reflect the adjustments to be made for a variety of beam loading conditions. The multipliers should be used in conjunction with the Beam Loading Chart.
The values in the Beam Loading Chart are based on a simple beam with uniform loading. By using the Beam Loading Conversion Table, you will be able to estimate the maximum recommended loading and deflection for your particular application. Solution: 1. From the load table on the next page, the maximum load for a 30" span is 2,224 lbs. and deflection for that load is 0.177". 2. Multiply by factors from the table below. 3. Thus, the 30" cantilever beam will support a maximum concentrated load of 267 lbs. on the end and that load will cause a 0.566" deflection. Load = 2,224 lbs. x 0.12 = 267 lbs. Deflection = 0.177" x 3.20 = 0.566"
Example: Determine load and deflection of a 30" 20P- 2100 cantilever beam with a concentrated load on the end.
