E = Modulas of Elasticity in psi. Many structures can be approximated as a straight beam or as a collection of straight beams. This section treats box beams with a single hollow portion in their cross section. Span of Beam (inches) Tributary width (inches) Uniform Load(pounds/square foot) e.g. The overall sizes of the beams were 115 mm X 395 mm X 5.4 m and 115 mm X 395 mm X 7.2 m. The box beams were assembled by nailing plywood webs to both sides of timber without the use of adhesives.
