Problem 1 Flexure: Behavior and Nominal Strength of Sections For the continuous beam shown in Figure1.1, f'c 3.5ksi, and fy = 60ksi. Compute the effective flange width bg for an interior T-section. Determine the bending strength oMn both for the positive and negative moment regions. At the supports, the No. 8 bottom bars are in one layer; at midspan, the No. 8 bars are in the bottom layer and the No. 7 bars in a second layer. Use 2.5 inches from the edge of the concrete (top and bottom) to the first row of bars and 2.0 inches to the second row of bars whenever applicable. Check Asmin VS As provided. Note the T-sections are spaced at 9ft-6 and 11ft as shown in Fig 1.1. Also, the stem thickness bw of the T-sections are 12, 12 and 18 inches from left to right. The overall length of the T-section is 22ft on center. The overall depth of the T-section h=21 inches. The thickness of the slab is 6 inches. B1-E in. 11 1 21 in Is in 12 in.
