L the length of span, and The most effective way of approaching the problem of efficient web thickness and hence correct design (4) shear stress is to test a number of beams of suitable over-all dimensions and various web thicknesses and In this abbreviated formula, (4), F is the axial load, E to… … Thickness of one web, inches shear are obtained by differentiating with respect to x. Figure 1.—The relation between load-weight ratio and thickness of web for 3 by 8^6 inch box beams with the grain of the plywood webs at ±45 degrees to the length of the beam. Flange depth V/i inches STRENGTH OF…
