From load table for W200 the load for a 60\and deflection is 0.35\B. Multiply by factors from Table aboveLoad = 700 lb. x 1.30 = 910 lbs.Deflection = 0.35\EXAMPLE IIPROBLEM:Determine load and deflection of an W150 cantilever beam with a concentrated load on the end.SOLUTION:A. From load table for W150 the load for a 24\5,360 lbs. and deflection is 0.09\B. Multiply by factors from Table above.Load = 5,360 lbs. x 0.12 = 643.2 lbs.Deflection - 0.09\Load and Support Condition Load FactorDeflection FactorSimple BeamUniform Load Span 1.00 1.00Simple BeamConcentrated Load at Center 0.50 0.80Simple BeamTwo Equal Concentrated Loads at 1/4 Points 1.00 1.10Beam Fixed at Both EndsUniform Load 1.50 0.30Beam Fixed at Both EndsConcentrated Load at Center 1.00 0.40Cantilever BeamUniform Load 0.25 2.40Cantilever BeamConcentrated Load at End 0.12 3.20Continuous BeamTwo Equal Spans - Uniform Load on One Span Span Span1.30 0.92Continuous BeamTwo Equal Spans - Uniform Load on Both Spans 1.00 0.42Continuous BeamTwo Equal Spans - Concentrated Load at Center of One Span 0.62 0.71Continuous BeamTwo Equal Spans - Concentrated Load at Center of Both Spans 0.67 0.48All Beam Load tables are for simple beams supported at the ends. These can be used in the majority of the cases. There are times when it is necessary to know what happens with other loading and support conditions. Some common arrangements are shown below. Simply multiply the values from the Beam Load tables by factors given below.60\60\24\
