prismatic beam having 250 mm x 500 mm is reinforced for flexure at the bottom with 4-ϕ20 mm with an effective depth of 420 mm. It is simply supported over a span of 6 m and designed to support uniformly distributed load over the entire span. Concrete weighs 24 kN/m3, Concrete strength f’c = 21 MPa and rebar strength fy = 280 MPa. 1. Determine the resulting depth of the uniform rectangular stress block in mm when the beam section reaches utlimate stage. (A to D) 2. Determine the nomina moment strength in kN/m of the beam section as per NSCP 2015. (E to H) 3. Determine the factored uniform load in kN/m the beam can sustain
