Fillet welds in joints resisting bending are interesting in that they can be simpler than those resisting torsion. From Prob. 933 you learned that your objective is to place weld metal as far away from the weld-bead centroid as you can, but distributed in an orientation parallel to the x axis. Furthermore, placement on the top and bottom of the built-in end of a cantilever with rectangular cross section results in parallel weld beads, each element of which is in the ideal position. The object of this problem is to study the full weld bead and the interrupted weld-bead pattern. Consider the case of Fig. 917, p. 479, with F 5 10 kips, the beam length is 10 in, b 5 8 in, and d 5 8 in. For the second case, for the interrupted weld consider a centered gap of b1 5 2 in existing in the top and bottom welds. Study the two cases with tall 5 12.8 kpsi. What do you notice about t, s, and tmax? Compare the fom9.
