a-Beam Design For Douglas Fir (north) #3 second floor, beam B1-B2 thickness is 3 inches determine the beam width. The beam stability factors are not a concern. The beam is loaded in bending about the minor axis. The beam is exposed to a moisture content about 25% and temperature variation about 120°F in a dry condition. The beams are spaced 2.5 ft on center, and they are subjected to flexure only. The beam is laterally supported. The wood is treated chemically.
