· Lapsplices in columns In multistorey buildings it would be ideal if each of the column's longitudinal rebars could be placed as one single piece throughout the structure's entire height. This however cannot be accomplished for practical reasons therefore, the length of the longitudinal rebars is equal to the height of each storey.

You can make a rough estimate by using thumb rule that about 80 kg of rebar is required per cum. of slab. So if slab size is say 10m x 10m x Concrete = 10 x 10 x = 20 cum. Therefore, Rebar = 80 kg x 20 = 1600 kg = MT. This method is often used to get a rough idea of the cost and weight of the steel that is used for the building ...
