How is column Bar bending Schedule calculated?
Bar bending schedule of a floor column Main Reinforcement: Find the length of the single main bar. Find the total length of the Main reinforcement. Calculate the weight of steel required per 1m of Main reinforcement. Find out the total weight of steel required for Main reinforcement.
What is the preparation of bar bending schedule?
Preparation of Bar Bending Schedule The major check lists before the commencement of BBS includes but not limited to the following: Check the concrete cover to each face. Check the lapping length for tensions and compression bars of each structural elements. Check the direction of bend of each bar.
How do you calculate Bar Bending Schedule for footing?
Steps involved in calculating the bar bending schedule of a footings:-
- Deduct the concrete cover to find the dimensions of bars.
- Find the Length of single X Bars & Y Bars.
- Find the total length of X bars.
- Calculate the weight of steel required per 1m.
- Calculate the total number of 12m bars required.
How do you calculate steel in a column?
We have a column. The height of the column is 3 m and having a cross-sectional area is 500 x 400 mm….HOW TO CALCULATE THE QUANTITY OF STEEL IN COLUMN (BBS)
| SIDE A | SIDE B |
|---|---|
| A =500 – 2 Side clear cover A = 500 – 2 x clear cover A = 500 – 2 x 40 A = 500 – 80 A = 420 mm | B =400 – 2 x Top & Bottom cover B = 400 – 2 x clear cover B = 400 – 2 x 40 B = 400 – 80 B = 320 mm |
How are bar schedules calculated?
Example of Beam Reinforcement Calculation:
- Length of B1 = clear distance between walls + 2 x width of walls – 2 x bar cover + 2 x bend length.
- Length of bar B2: A + B + C = 4000 + 2 x 230 – 2 x 40 + (1.414xH – H)
- B2 = 4000 + 2 x 230 – 2 x 40 + (1.414×334 – 334) = 4518.3 = 4520mm.
How do you calculate bending rebar length?
How To Calculate Bend Deduction Length Of Bar
- For 45° bend = 1 x d.
- For 90° bend = 2 x d.
- For 135° Bend = 3 x d.
- For 180° bend = 4 x d.
What is Barbar bending schedule?
Bar Bending Schedule is a list of bar according to the drawing of any structure or element. It includes the cutting and bending length of bar according to bar diameter. For any heavy or complex structure, its reinforcement calculation is very difficult so we are providing a simple calculation sheet for BBS in Excel sheet.
How to calculate the bend length when bars are bent at corners?
(ii) Bend Length calculation when bars are bent at corners:- 1 45° Bend length = 1d 2 90° Bend length = 2d 3 135° Bend length = 3d More
How to prepare for steel bending project?
Ensure to follow the IS guidelines for bending, hook length, lap length & development length calculations. It would be handy if you memorize the unit weight of steel bars. Ensure the estimation by thumb rule calculations of steel reinforcement for different structural members. Keep Bar Bending Shape Codes handy for easy reference.
Is cutting length and bending length included in the detailed list?
The cutting length and bending length calculations are separately calculated and not included in the detailed list. Like I have listed the Bar Bending details in a table and calculations are done separately. BBS helps to estimate the total quantity of steel required for the construction of building or structure.
