Determine the nominal capacity (Mn) as well as the design moment capacity (6Mn) for the doubly-reinforced beam cross section shown in Figure 1 in positive bending (i.e., tension on bottom, compression on top). You may assume that f. = 4000 psi and that fy = 60,000 psi. Use the iterative strain compatibility analysis outlined in class, and iterate until the strain changes by less than 5% in successive iterations. 12.5 in. 2 No. 9 Bars 24 in. 6 No. 10 Bars Figure 1
