N.a.C.a. Technical Note No. 469 12 are in the direction of the flanges. Hence, equation (2) or (5) gives only the horizontal component of the flange forces; the total flange forces and their vertical compo- nents are easily computed from the horizontal components and the inclination of the flanges. … The vertical components of the flange forces carry a carried by part of the shear. accordingly, the shear Sw S and the web is the difference between the total shear the vertical components of the flange forces: (13') + tan 6 q) S - S (tan 6 m h 1 (See fig. 10.) This shear Sw is used to calculate…
