Calculating the amount of steel bar for reinforced concrete beams
For example, if we are going to make floor beams measuring 20 cm x 30 cm with a length of 3m, the main reinforcing steel we will use has a diameter of 10 mm, totaling 8 rods, while for shear stirrup we use steel bar of 8 – 200 (read: 8 mm diameter steel bar installed 20 cm apart). Requirements for main reinforcing steel of D10 In the beam, there are 8 pieces of steel 10 mm in diameter, each 3 m long. So the total requirement is 8 pcs x 3 m = 24 m. If the length of steel bar on the market is 12 m per rod, then the steel bar requirement is 24 m : 12 m = 2 rods. Requirements for shear stirrup of D8 For every 3 m of a beam, how many pieces of shear stirrups are there? We can calculate this by means of 3 m : 0.2 m = 15 pcs. How long steel bar is required for one shear stirrup? We can calculate it by adding up the circumference of the shear stirrup, which is 0.15+0.25+0.15+0.15+0.05+0.05 = 0.9m. So, the total requirement for shear stirrups is 15 pieces x 0.9 m = 13.5 m. In the same way, ...
