Problems 2 and 3 refer to the floor plan shown in Fig. 2. S CI C2 C3 C4 CS C7 typ.) C6 C8 Given: L = 25' (typ.) and S = 10 (typ.). So, the overall floor plan = 75' x 60 L 111 (typ) The beam width (bw) and depth (h) of 81 (typ.) are taken to be 10-in and 20-in, respectively. BI () B1 (typ) СУ CIO ci1 C12 A typical girder, e.g., G1, has a width (bw) of 12-in. GI (typ) C13 C14 C15 C16 Fig. 2 - Floor Plan for Problems 2 & 3.
Problem 3. The beams, e.g., B1 (typ.), are also cast with fe' = 5,000 psi (normal weight concrete, 150 pcf. B.=0.8). Use d = h-3", for both positive and negative bending. (a) (10 points) Determine per AC1318 the effective flange width (be or by) of a typical beam, B1, subjected to positive bending. (b) (20 points) Use where applicable a b. (or by) of 76-in [i.e., ignore the one calculated in part (a)}, compute the minimum flexural reinforcement required fi.e., A, mm) and its corresponding design bending (M.) of B1 for positive bending only (c) (20 points) Use where applicable a b. (or b) of 76.in fi.e., ignore the one calculated in part (a)], compute the maximum flexural reinforcement required (l.e., Asma) and its corresponding design bending (M.) of B1 for positive bending only. Use & -0.005, Bonus credit: (d) (10 points) If No. 4 U stirrups at 8" on-center are used for BI, determine the design shear capacity (V.) of the beam.
