How do you calculate pile cage length?
CIVIL ENGINEERING TUTORIAL Depth of pile /Pitch + 1 = 20/0.1 + 1 = 201 numbers. So, for 20 meters pile, 884.4 meter long spiral should be cut. d2 / 162 = 12 x 2 / 162 = 0.888 kg. Quantity of 12 mm dia bar = Total cutting length x unit weight = 884.4 x 0.888 = 785.35 kg.
How do you calculate spiral reinforcement in piles?
How to calculate the cutting length of spiral stirrups(ring). / Calculating the cutting length of helical ring( stirrup ) for pile.
- =n√C2 + P2.
- = n√C2 + P2.
- = 122 × √2.0172 + 0.152.
How do you make BBS of pile cage?
From the diagram, Height of the pile – 20m or 20000 mm. Diameter of Pile – 600 mm. Clear Cover of the pile – 75mm….
- Step 1 – Calculate the Length of Vertical Bar.
- Step 2 – Calculation of Number of Inner Spacer Ring & Length of Each Ring.
- Step 3 – Calculation of Number of Outer Helical Ring & Length of Each Ring.
What is Lap length in reinforcement?
The lap length is the length provided to overlap two rebars in order to safely transfer load from one bar to another bar and an alternative to this is to provide mechanical couplers. It is also known as lap splices.
What is Anchorage length in rebar?
Meaning of anchorage length is the length required for development of stress in the rebars, this is obtained by providing the required development length or hook/bends if sufficient length cannot be achieved.
What is the lap length in reinforcement?
Normally, lapping position is at where near the minimum shear force is acting. Normally lap length is 50D meaning 50 times the bar diameter if both bars are of same diameter. When lapping two bars of different diameters, the lap length is considered as 50 times the smaller diameter.
What is the 5 pattern in nature?
Spiral, meander, explosion, packing, and branching are the “Five Patterns in Nature” that we chose to explore.
What is the purpose of spiral reinforcement?
The purpose of this type of reinforcement is to retain the main bars in exact position. The height or depth of the column is taken as 10 feet. The gaping among each spiral is 2 feet. The gaping gapping among two successive spiral is known as pitch. To determine the length, the following formula is used:
How many pitches are completed for Spiral Bar in this pile?
2nd find out the no of spirals and then the how many no of laps are required in the total length of the spirals. = 2800 mm or 2.8m Ans.. 101 nos of pitches are completed for spiral bar in this lenght of given pile. We know that length of one full bar is 12m so lapping are required in this case.
How do you calculate the weight of a Spiral Cage?
Count the spirals in one cage, and multiply by the number of cages to estimate the total, or weigh one spiral, and one cage. Then fill the cage with spirals and weigh it.
How do you calculate the amount of steel in a cage?
Count the spirals in one cage, and multiply by the number of cages to estimate the total, or weigh one spiral, and one cage. Then fill the cage with spirals and weigh it. How much quantity of steel required for 1m3 concrete? Quantity of steel is not dependent on the volume of concrete, but on the structure where it is being used.
