How do you calculate steel piling?
How do you calculate steel piling?
From the Figure:
- Length of Pile = 20m.
- Diameter of Pile = 0.6m.
- Diameter of: Vertical Reinforcement = 20mm – 12nos. Outer Helical Ring = 8mm @ 200mm c/c. Inner spiral ties = 16mm @ 2000mm c/c.
- Bottom Length of Anchorage = 300mm.
- Development Length = 40d.
- Clear Cover = 75mm.
How do you measure a steel cage?
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 the weight of a spiral reinforcer?
To solve the quantity in kilograms, follow the steps below : a) Compute the net diameter of bored pile, i.e. diameter of bored pile less clear concrete cover, say 50 mm. Hence, net diameter = 1.5 m – 2*0.05 = 1.4 m. f) Finally, total quantity of spirals expressed in kgs = total length x unit weight = 785.35 kgs.
What is pile cage?
Pile cages are used to support weight loads and protect the earth from general or seismic movement that can collapse the structure. Once the pile cavity has been bored, reinforcing steel cages are lowered into the hole with spacer wheels maintaining clearance from the bored hole edges.
How do you calculate the length of a spiral pile?
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 × √2.0292 + 0.152.
How many types of spirals are there?
Spirals are classified by the mathematical relationship between the length r of the radius vector, and the vector angle q, which is made with the positive x axis. Some of the most common include the spiral of Archimedes, the logarithmic spiral, parabolic spiral, and the hyperbolic spiral.
How do you calculate pile distance?
Cohesion Piles: Spacing S = 3.5d + 0.02L Here d is the diameter of the pile and L is its length.
