Problem No. 2 A three-span continuous beam will carry the gravity loadings patterned as shown in Figure 1, (all loads are factored). The design properties used are: f'c = 28 MPa; fy = 415 MPa, Es = 200,000 MPa, 40 mm clear cover and 25 mm-diameter main bars. a) Analyzed the continuous beam Hardy-Cross Method (or moment distribution method) and draw the shear and moment diagrams indicating the points of maximum moment and shear. b) Design a prismatic beam dimension (uniform beam size from A-D) based on the maximum bending moment with p = Po.005 c) Design the number of bars at the point of maximum negative bending moment and maximum positive bending moment only. d) Design the spacing of 10-mm diameter U-shaped stirrups at support "C" for span 20 KN 20 KN 30 kN/m 2 m 2 m 2 m 20 kN/m ) A B с D 6 m 5 m 4m Figure 1
