Every civil engineer must know the method of calculation steel quantity from drawing. The steel calculation formula is L x D2 /162 where, Lets take a example, we have a column size 450 x 600 x 3000 mm. The beam is a structural element that transfers all the dead load, the live load of the slab to the column. Cutting length of ties A = (column width – clear cover + column thickness – clear cover) + 2 no. These types of beams are often used in trusses in buildings. 6. Steel Bars Used for Plinth Beam. Plinth Beam. beam effect. 5. Example: Let us we have a simply supported beam having a cross section 300×500 mm and length of the beam is 4 m.The main bars used in this beam is 20 mm and the support bar diameter is 16 mm.The diameter of the stirrup is 12 mm and the spacing of stirrup is at an end is 100 mm and 150 mm at the mid support of the beams.. A , B, C, and D. Dia of ties is 8 mm. of bar of long span= 5320 / 150 +1 = 36.46 , approx = 36, Cutting length of short span = Length of span + Crank length – 45° bend, D = Slab thickness – 2 side clear cover – dia of bar = 150 – 50 -10 = 90 mm, = 3721.5 + 0.42 x 90 – 2 x 1 x 10 = 3739 mm, Total cutting length = 26 x 3.739 = 97.21 m, Cutting length of Long span = 5320 + 0.42 x 90 – 2 x 1 x 10 = 5337.8 mm, Total cutting length = 36 x 5337.8 = 192.16 m, Weight of short span bar = 97.21 x 0.617 = 59.97 k.g.
