Window headers are usually built of two pieces of dimensional sawn lumber placed side-by-side. Like other pieces used in wall systems, window header thickness is limited by the depth of the wall. Most wall systems use two-by-fours, which are actually 3-1/2 inches wide. Greater strength for beams can be achieved by using thicker beams.Figure 5 - This figure illustrates 2 structural elements: a structural ridge beam and a center girder. Both have a tributary area of 12'0". The load per foot of beam is determined the same way as for headers. Ridge Beam Conditions Girder Example The center beam carries half of the floor load, the partition load and half of the second floor load.
