What Is Development Length?
Develop a secure bond between the surface of the bar and the concrete so that any failure due to slippage of the bar does not occur during the final load conditions.
Furthermore, the additional length of the bar provided as the length of the growth is attributed to the stresses developed in any section of adjacent sections (such as the additional length of the bar provided from the beam to the column at the column beam junction).
Image A: Development length is provided at the beam and column junctions. The stresses developed due to this are easily transferred by bonds created by steel and concrete.
Image B: The length of the growth at the beam and column junction is not provided. Due to this, the tension developed in the beams will not be able to transfer it to the column.
Lap length: The lap length is the minimum length that must be generously provided if the two bars are joined together so that forces can be easily transferred.
Image D: Check the lap splice in the beam. The length of the overlap varies depending on the flexural tension, direct tension, and compression. In our practical site condition, it is taken to be approximately 50 x the diameter of the bar.
Image E Overlapping is done in most columns because the column can reach more than 100 m. The bars are cut in every other story of the building to simplify the work for the workers.
Align a tape measure along the center of a pipe and measure the pipe's length. Write down the measurement. For example, the pipe might be 8 inches long.
Write down the appropriate measurement for the fitting that is used on the specific type of pipe. For example, the socket depth for a 1-inch plastic pipe is 3/4 inch.
Multiply the fitting measurement times 2 to account for the fittings on either end. Using the previous example of a 3/4-inch fitting, you would multiply 3/4 times 2 to get 1 1/2 inches.
Add your answer from Step Three to the length from Step One to get the determined length of the pipe. In this example, you would add 1 1/2 to 8 to get a determined length of 9 1/2 inches.
