Solution: EXAMPLE 1-10 Two wood box beams (beams A and B) have the same outside dimensions (200 mm x 360 mm) and the same thickness (t 20 mm) throughout, as shown in the figure. Both beams are formed by nailing, with each nail having an allowable shear load of 250 N. The beams are designed for a shear force V 3.2 kN.

A further variation of the runway is a lift shaft lifting beam. Although such beams are usually intended for use with a fixed point lifting arrangement, their design and testing requirements are the same criteria as runway beams.
