Question
For the beam and loads shown, using Table 4.1, propose the following if f'c = 24 Mpa, fy = 420!
1) The initial b x d dimensions of the beam using normal weight concrete with 23.5 kN/cu.m. a
density. Base your answer on what you have learned so far.
2) Final dimensions of the beam if the tensile steel area, As = 0.4pb (bd).
3) The positive and negative reinforcements. Hint: consider the two critical sections only.
4) Using the results in 3), draw the beam cross section proportionately with reinforcements. S
the necessary concrete covering calculations base on the chosen bar diameter. Assume that
stirrups are 10mm in diameter.
