ear of J = 40,000 lbs.Since each rivet can safely endure a shear of 9000 lbs. in doubleshear (see p. 294), the number of rivets required in the height ofweb would be 40000 ~ 9000 = 4.44; i.e., they should be spaced4.5 in. apart since the height of web is 20 in., and 20^ ~ 4.44 =4.5^. But since the… … Fig. 123. of web should be 40,000 -^ 5470 =: 7.2, which implies puttingthem at a distance apart, centre to centre, of 20 -f- 7.2 = 2.7 in.This spacing, therefore, should be adopted in the horizontal seambetween web and angles at this part of the beam (near abutment).100.
