The length is calculated by a number of factors. The most basic example is as follows. Say a bar is required to be u shaped. It is to be placed in a 12" wide block. The bar bend would be the length of the block (12") minus a clearance on each side of the block. This clearance allows protection to the bar from weather and moisture. Typically the clear dimension is 2" or 3", depending on location in structure and engineer's specifications. That said, assuming a 2" clearance, the above example would be 12" - 2" - 2" = 8". That dimension is the out to out dimension of the rebar for that side of the bend.

How to calculate length of steel AT 45 degree bend?
To calculate the length of steel at a 45-degree bend, you can use the formula for the length of the bend, which is typically derived from the radius of the bend. For a 45-degree bend, the effective length of the bend can be calculated using the formula: Length of bend = (π/4) × Diameter of the pipe or bar. Additionally, if you have the radius of the bend (R), the length can be approximated as Length = R × (π/4). Always consider adding straight lengths before and after the bend to get the total length.
How to calculate dimension 90 degree bend in BBS?
To calculate the dimension of a 90-degree bend in a Bar Bending Schedule (BBS), you need to determine the bend radius and the length of the bent bar. The formula typically used is: Length of bend = (π/2) × Bend Radius + Straight Length before and after the bend. Ensure to account for the bar diameter when determining the bend radius, as it affects the overall length. Finally, sum these lengths to get the total dimension for the 90-degree bend.
How do you calculate the degree of a bend?
To calculate the degree of a bend, you can use the formula: Degree of Bend = (Arc Length / Radius) × (180/π). Measure the arc length of the bend and the radius of the bend. Then, plug these values into the formula to obtain the degree of the bend in degrees. This method is commonly used in fields like metalworking and pipe fitting.

What is the weight of 9mm rebar?
The weight of 9mm rebar (also known as #3 rebar) is approximately 0.39 kg per meter (or about 0.26 pounds per foot). To calculate the total weight for a specific length, you can multiply the length in meters by 0.39 kg/m. For example, a 10-meter length of 9mm rebar would weigh around 3.9 kg.

What is the weith 168x27-7 rebar?
You need the size of the rebar involved to calculate the weight. Charts can be found at CRSI.org or Rebarapps.com. Than take that and multiply it by the the length of the rebar. For example, a #4 rebar weighs 0.668 lbs/ft. If you have 5 @ 20-00 pieces that is 0.668 X 20 X 5 = 67 lbs. You need to know the size of the bar to calculate.

How do you calculate rebar y16 to ton?
To convert rebar from diameter (e.g., Y16) to tons, first determine the weight per meter of the rebar. For Y16 rebar, it typically weighs about 1.58 kg per meter. Then, measure the total length of rebar in meters, multiply it by the weight per meter, and divide by 1,000 to convert kilograms to tons. For example, for 100 meters of Y16 rebar, the calculation would be (100 m * 1.58 kg/m) / 1,000 = 0.158 tons.
What is the formula to calculate rebar weight?
You have to find a chart that will indicate the weight per unit of measure for the appropriate rebar size. Than take that and multiply it by the the length of the rebar. For example, a #4 rebar weighs 0.668 lbs/ft. If you have 5 @ 20-00 pieces that is 0.668 X 20 X 5 = 67 lbs. Charts are available throughout the web or at CRSI.org.
What is the difference between lap splice length and development length for rebars?
The difference between the two is in the application. A development length is the amount of rebar length that is needed to be embedded or projected into concrete to create a desired bond strength between the two materials. The lap splice length is the length two rebar pieces must overlap and be tied together to create a bond as if there was no break and the run is "continuous". So simply put, development is rebar to concrete, splice is rebar to rebar. The lengths of both splice and development do vary. They are dependent upon different factors. These include but are not limited to concrete strength, rebar size, rebar coating and concrete cover or clearance. So when you see a chart on one project, it can differ from another for these reasons.
How do you bend the rebar?
Either just grab it and bend it around something or use a length of pipe, stand on one side and slide the pipe over the other end and bend it. You can stick it in something solid and bend it with the pipe then.
