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. 40 kN 50 kN 30 kN D= 20 kN/m L= 30 kN/m A 3m 3m 3m 4m
