Design the torsional and shear reinforcement for the beam as shown in the figure. The resulting L beam supports a live load of "A" kN/m along the beam centerline plus "E" kPa uniformly distributed over the upper slab surface. Assume clear cover 40 mm and "F" diameter stirrups. Use the unit weight of concrete 23.60 kN/m³. Round off your initial calculations and final answer by 3 decimal places. b

Question
Design the torsional and shear reinforcement for the beam as shown in the figure. The resulting L beam supports a live load of "A" kN/m along the beam centerline plus "E" kPa uniformly distributed over the upper slab surface. Assume clear cover 40 mm and "F" diameter stirrups. Use the unit weight of concrete 23.60 kN/m3. Round off your initial calculations and final answer by 3 decimal places. Given: L = 13 width of column = 0.6 m z = 2.3 Over-all depth of beam, h = 725 mm Width of beam, b = 350 mm Thickness of slab, t = 125 mm Effective depth, d = 660 mm f'c = 35 MPa Yield strength of flexural steel, fy = 414 MPa Yield strength of stirrups, fyt = 275 MPa A = 7 kN/m E E E
