a. Main reinforcement (short span i.e the bars are parallel to the short span), Y12, shape code 34 @ 125 mm centre to centre, b. Distribution reinforcement (long-span i.e the bars are parallel to the long span), Y 10, shape code 20 @ 300 mm centre to centre, c. Concrete cover, 30mm, d. Concrete strength, 40MPa. Draw the reinforcement layout for this slab, in plan and section, indicating all the reinforcement and necessary information required by the contractor.
QUESTION 1
A concrete floor slab measuring 6 m x 3 m is simply supported on one side brick load-bearing walls along the 6 m sides. The concrete slab is 200 mm thick and reinforced at the bottom as follows.
a. Main reinforcement (short span i.e the bars are parallel to the short span), Y12, shape code 34 @ 125 mm centre to centre,
b. Distribution reinforcement (long-span i.e the bars are parallel to the long span), Y 10, shape code 20 @ 300 mm centre to centre,
c. Concrete cover, 30mm,
d. Concrete strength, 40MPa.
Draw the reinforcement layout for this slab, in plan and section, indicating all the
reinforcement and necessary information required by the contractor.
Calculate and indicate the number of bars required on your drawing.
You do not need to calculate the bar lengths and the curtailment. Neat drawing please
