A rectangular concrete beam has a width of 300mm and an effective depth of 550mm. The beam is simply supported over a span of 6m and is used to carry a uniform dead load of 35kN/m and uniform live load of 40kN/m. Assume fc= 21MPa and fy= 312MPa. Compression reinforcement if necessary shall be placed at a depth 80mm from the outermost compression concrete. Which of the following most nearly gives the required number of 25-mm tension bars?

Question
A rectangular concrete beam has a width of 300mm and
an effective depth of 550mm. The beam is simply
supported over a span of 6m and is used to carry a
uniform dead load of 35kN/m and uniform live load of
40kN/m. Assume fc= 21MPa and fy= 312MPa.
Compression reinforcement if necessary shall be placed
at a depth 80mm from the outermost compression
concrete.
Which of the following most nearly gives the required
number of 25-mm tension bars?
