You can do it the tedious way of counting and multiplyng the bars in the slabs and then adding lap lenghts in Slabs Columns and Beams. But I will let you in a little time saving secret I learned way back in University. We had some real good lecturers in London. They all were working in the various branches of sstructural engineering.

In this case. So. It is this. I have been using that formula for 40 years and its still good. And that is all you need when you are doing estimation of Quaantities. vi) Spacing between the bars vii) Length of the bar in the direction of the bar you considered. v) Diameter of the bar as mentioned in reinforcement drawings. since it is a rectangular slab the volume = Length x Width x Thickness. So the rule is; (Cubic Yards of Concrete X 125 pounds) = amount of reinforcement in pounds. Good luck Written Jun 1. which shows how to make a table for easy calculations of reinforcement quantity in a slab. There are types of direction in the slab I considered namely longitudinal and transverse. It is a slab with a bar showing in longitudinal direction https://www. I explain one by one how I arrive at them.com/HowdoIcalculatesteelreinforcementanditsquantityinslabbeamscolumnsandfootingforgivendimensions 2/6 . Again this entirely depends but this will help you to bifurcate the reinforcement while doing complex calculations. iv) Layer There can be more than a single layer of reinforcement. ii) is valid for this point too. beams.2/21/2016 (1) How do I calculate steel reinforcement and its quantity in slab. ii) Face You can keep any nomenclature you want to. vii) Extend of the bar is the distance/length for which the bar is extended with its uniform spacing in perpendicular direction. This will be helpful at the end of weight of reinforcement calculation. I make a table like below for most of such calculations: Now I elaborate how the above table works: a) Before getting into table calculate the volume of the concrete quantity. giving different names to different layers helps you a lot. Since the slab. columns and footing for given dimensions? Quora taught us Quantities had his own QS firm and he gave us the secret to estimating steel reinforcement in a concrete building. b) There are total 13 column in the table. i) Serial number. That will give you a close approximation of the steel that will be necessary in the building. For more clarity refer the following image. which I considered has both top and bottom reinforcement to avoid further confusion I gave top layer as near face and bottom layer as far face. 2015 • View Upvotes Upvote 32 Downvote Comments 2+ Share 1 Varun Chowdary.

Concrete beams Structural drawing present information like number of top and bottom bars. Multiply this is number of stirrups required and you get the quantity of steel required in stirrups. except for the fact that column ties go into the joints not face to face. As a person who is calculating quantity of steel. Let me shed some information from a structural engineers perspective as how we provide information on our drawing and how you can calculate reinforcement quantity from it. That is how you come up with bar length required for stirrup and you again add some hook lengths as mentioned in drawings. For further assistance regarding this topic you can contact me. what you should do is multiply the quantity with desired length of bars mentioned in the drawing. Now subtract two sided covers from each side and you will get a number corresponding to each breadth and depth. columns and footing for given dimensions?
