t and ultimate stresses in timber under compression along the grain due to the support which a low-stressed fiber may give to one more severely stressed is developed later in this report. When attempting to evaluate the amount of reinforcement received by the extreme compressive fiber from those… … Fig. 3.—Equivalent beam sections. Fig. 4.—Matching diagrams. Curve B is the supporting ratio of the flange of a box or I beam. The depth of compression flange in per cent of total depth of beam is plotted against the ratio of the area above this flange-depth ratio to the total curve A area. Figure…
