Question
A simply supported beam is reinforced with 5-25mm-diameter at the bottom and 2-20mm-diameter at the top of the beam. Concrete covering to centroid of reinforcement is 70mm at the top and 64mm at the bottom of the beam. The beam has a gross depth of 450mm and gross width of 300mm. f’c = 28MPa, fy = 415MPa. Assume bars laid out in single layer. Calculate the following if the limiting tensile steel stain is 0.004 for a ductile failure :
Depth of the neutral axis from the extreme concrete compression fiber to the nearest whole number =
Design strength of the beam section to the nearest whole number =
Maximum service uniform live load over the entire span in addition to a DL = 20 kN/m (including thr weight of the beam) if it has a span of 6m =
