![]() It improves the quality control at the site as reinforcement is provided as per bar bending schedule which is prepared using the provisions of respective detailing standard codes.Ĥ. Using a bar bending schedule when used for Fe500, saves 10% more steel reinforcement compared to fe415.ģ. This increases faster execution at the site and reduces construction time and cost due to less requirement of workers for bar bending.īar bending also avoids the wastage of steel reinforcement (5 to 10%) and thus saves project costs.Ģ. When Bar bending schedule is available, cutting and bending of reinforcement can be done at the factory and transported to the site.

Width of Slab at one end for bent up at Top L = 3.61 In case of bent up bars are provided on both sides, we have to add 0.45 X twice in length ) L = 3.58 m (Straight length without bent) L = Span Length + Wall Width(Right) + Wall Width (Left) + 2 x 9D (Hooks) – 2xCover 180 c/cġ2 mm dia main Steel 150 mm c/c Alternate Let’s take the example of RCC slab reinforcement to calculate and prepare Bar Bending Schedule. Read More: Steel Quantity Calculation Excel Sheet How to Prepare Bar Bending Schedule Refer to “IS:2502 Code of Practice for Bending and Fixing of bars” for further information. even though the angles are 45 degrees, 90 degrees,135 degrees, 180 degrees we will deduct only 2d for each bent). Note: Practically in the construction site we will be deducting only 2d for a single bend irrespective of the angle (i.e. Length=12m, Diameter=25mm, bent angle= 90 degree & no of bents are 2. ![]() Note: For n number of bends there should be n deductions in the original length to get the cutting length. So for one bend, it is deducted by 4d as it is 180 degrees bendĬutting Length = 12- 3d= 12- 4*0.025= 11.900 m. 180° Bend In Steelįor example, if the length of the bar is 12 m (assume), the diameter is 25 mm. Similarly for a 180-degree bend, the deduction is 4d. So for one bend, it is deducted by 3d as it is 135 degrees bend.Ĭutting Length = 12- 3d= 12- 3*0.025= 11.925 m.Ĥ. 10×10 Room Construction Cost Excel Sheetįor example, if the length of the bar is 12 m (assume), the diameter is 25 mm.Construction Material Testing Menu Toggle.30×40 House Plans | 1200 sq ft House Plan.20*50 House Plan | 1000 sq ft House Plan.How to become a Civil Engineering Surveyor.The benefits of civil engineering surveying.The different types of civil engineering surveying.What is the role of Surveying in Civil Engineering?. CIVIL ENGINEERING FORMULAS IN URDU HOW TO Surveying is the process of determining the relative positions of points on the Earth’s surface. It is mainly used in the construction industry to determine the size, shape, and location of buildings and other structures. ![]() Surveying can also be used for environmental purposes, such as determining the boundaries of a piece of land.Īs a civil engineer, you may be involved in surveying at some point in your career. Surveying is the process of determining the relative positions of different points on the surface of the earth. ![]() It is used to create maps and other diagrams that are used in planning and construction projects.
