Question

The hollow box beam has a span of 12.4 m. it is reinforced for shear with 10 mmø bar. The beam carries a factored concentrated load of Pu = 136 kN at a point 4.1 m from the left end of the simply supported beam, and a total uniform factored load of 14 kN/m distributed throughout the entire span. f'c = 19.5 MPa, fy = 413.4 MPa and fyt = 253 MPa. Use normal weight concrete. For the beam dimensions: b = 490 mm, bh = 290 h1 = 130 h2 = 235 and concrete cover cc = 55 mm. Answer the following: (1) Determine the distance from the left support where the stirrups can be omitted using the simplified calculations. (2) Determine the shear strength of the stirrups spaced at d/2 mm apart. (3) Determine the factored shear force of the beam with stirrups spaced at d/2 mm apart.
