Updated August 27th, 2017There is a formula to calculate the unit weight of steel bars. I'll come that point later. Why do we need to know the unit weight of steel bars? When we estimate the steel bars for a Reinforced Concrete member we get the length of that as a result. For example, 1000 […]
Bar bending schedule provides the reinforcement calculation for reinforced concrete beam. It provides details of reinforcement cutting length, type of bends and bend length. We will take one example for reinforcement quantity calculations for a concrete beam.
Steel Reinforcement Bars and its Important Characteristics Steel reinforcement bar is also known as rebar, reinforcing bar, reinforcing steel and reinforcement steel. It is a versatile constructional material which is widely used in the construction industry for making of the reinforced concrete.

plz tell me the formula for calculating the steel?.. Answer / mr. ajay kumar singh Dear concern person his proper formula or proper pattern is only bar bending schedule of steel (BBS of reinforcement) of respectively Column, beam and slab.
FIGURE 1.19 Spacing of steel bars (a) in one row or (b) in two rows. 1.8.2 Concrete Cover The specified minimum concrete cover for different structural members, according to their degree of exposure, is given in the Egyptian Code, Table 4-13.
Cutting length of bar = (length of the member – deduction for cover on both sides) + development length. 5. Then calculate the unit weight of each dia bars by the following formula: W = d^2/162. Where d is the dia in mm and weight (w) in kg.
