Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.

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.1. Main reinforcement (short span i.e the bars are parallel to the short span), Y 12, shape code 34 @ 125 mm centre to centre,2. Distribution reinforcement (long span i.e the bars are parallel to the long span), Y 10, shape code 20 @ 300 mm centre to centre,3. Concrete cover, 30mm,4. 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. You must calculate and indicate the number of bars required on your drawing. You do not need to calculate the bar lengths and the curtailment. Your drawing must be neat.
