The short cuts are intended only for the design of.
Makes effective use of the short cuts and demonstrates them in the examples provided later in the chapter.
For the initial calculation f can be estimated at 1 000.
Beam design example choose the lightest wide flange steel section available to support a live load of 790 plf and a dead load of 300 plf over a simple span of 18 feet.
Use f y 50 ksi.
In the example the beam spans the 10 foot width of the roof.
