Question

4.3 A simply supported beam is reinforced with 5-ϕ25 mm at the bottom and 2-ϕ20 mm at the top of the beam. Concrete covering to centroid of reinforcement is 70 mm at the top and 64 mm at the bottom of the beam. The beam has a gross depth of 450 mm and gross width of 300 mm. fc’= 28 MPa, fy = 415 MPa.  Assume bars laid out in single layer.

Calculate the following if the limiting tensile steel strain is 0.004 for a ductile failure:

Calculate: Maximum service uniform live load over the entire span in addition to a DL = 20 kN/m (including the weight of the beam) if it has a span of 6 m =  _____?____  kN/m (to the nearest whole number)
