TutorBin Question Problem 1: Compute the following quantities: 1x, ly, rx ry, S., and Sy for the shape W30x211. Compare your computed values with those tabulated in Part 1 of the AISC Steel Construction Manual (AISCM). Neglect the fillet areas in your calculations. (Hint: Divide the shape into three rectangles. AISCM Table 17-27 provides formulas for some basic sections.) Problem2: A built up I-shape shown in Figure 1 is used as a simply supported beam subject to a uniformly distributed load. Use A572 Grade 65 steel. (A) Locate the elastic neutral axis (ENA) measured from the bottom of the section. Compute the elastic section modulus, S., with respect to the top flange. (B) Locate the plastic neutral axis (PNA) measured from the bottom of the section. Then compute the plastic section modulus, Zz. 21" 7/8" x 16" 5/8" Î7/8" 12" Figure 1
