A cover-plate beam is made up of a W21x147 section with 300 mm x 12 mm plates attached to the top and bottom flanges and is fastened by two rows of 20 mm rivets. The beam is simply supported over a span of 6m and carries a uniformly distributed lead of 270 kN/m including its own weight. The shear capacity of each rivet is 30 kN. Properties of W21x147 Overall depth, d- 560 mm Moment of Inertia, I- 0.00151 mm fange W21x147 FIGURE 18 Determine the distance from the centroid of the cover plate to the neutral axis of the built-up section. Determine the moment of inertia of the built-up section about its neutral axis. Determine the longitudinal pitch of the rivets.
