How To Calculate The Anchor Bolt For The Octagonal Foundation
An Octagonal Foundation refers to a structural base or footing This is geometrically shaped like an octagon, a polygon with eight sides and eight angles. The design of an octagonal foundation is based on principles of geometry and structural engineering, aiming to distribute the weight of the building evenly across its surface area. How To Calculate The Anchor Bolt For The Octagonal Foundation
Uses of Octagonal Foundation
This type of foundation is utilized in various architectural and engineering contexts to provide stability and support to structures built above it. This foundation is used for verticle vessel vertical columns or tanks. The construction of an octagonal foundation typically begins with site preparation, including excavation and leveling of the ground. Reinforcement materials such as steel bars or mesh may be added to enhance the foundation’s strength and durability.
How To Calculate The Anchor Bolt For The Octagonal Foundation
We will discuss how to find the coordinates of anchor bolts for octagonal foundations with the help of some given data. given data means the center point coordinates are given.
The formula for calculating the Coordinates for octagonal foundations
Easting = sin∅ x radius +center point Easting
Northing = cos∅ x radius +center point Northing
Given data
Radius of Foundation = Dia / 2 = 1750 / 2 = 875
Easting of center point = 61554.492
Northing of center point = 44736.450
Number of bolt = 16
Angles Anchor Bolt C/C = 22.5º
Solution
Angles Anchor Bolt C/C = 360º / Number of Bult
Angles Anchor Bolt C/C = 360/16 = 22.5º
The angle of the first anchor bolt = Angles Anchor Bolt C/C / 2
The angle of the first anchor bolt = 22.5º / 2 = 11.25º
The First Anchor bolt Coordinates
Easting = sin∅ x radius +center point Easting
Northing = cos∅ x radius +center point Northing
Easting = sin (11.25) x 0.875 + 61554.492
Easting = 0.1707+ 61554.492 = 61554.663
Northing = cos (11.25) x 0.875 + 44736.450
Northing = 0.858+44736.450 = 44737.3087
The 2nd Anchor bolt Coordinates
Now the 2nd anchor bolt is angle is 22.50º + First anchor bolt’s angle is 11.25 = 22.50+11.25=33.75º
Easting = sin(33.75) x 0.875 + 61554.492
Easting = 0.486 + 61554.492 = 61554.978
Northing = cos (33.5) x 0.875 + 44736.450
Northing = 0.727+ 44736.450 = 44737.177
Now others all anchor to find the same procedure and formula
The 3rd Anchor bolt Coordinates
Use the angle =33.75+22.5 =56.25º
The 4th Anchor bolt Coordinates
Use the angle =56.25º+22.50 = 78.75º
The 5th Anchor bolt Coordinates
Use the angle =78.75º+22.50 = 101.25º
The 6th Anchor bolt Coordinates
Use the angle =101.25º + 22.50 = 123.75º
The 7th Anchor bolt Coordinates
Use the angle = 175.25º + 22.50 = 1146.25º
The 8th Anchor bolt Coordinates
Use the angle =146.25º + 22.50 = 168.75º
The 9th Anchor bolt Coordinates
Use the angle =168.75º + 22.50 = 191.25º
The 10th Anchor bolt Coordinates
Use the angle =191.25º + 22.50 =213.75º
The 11th Anchor bolt Coordinates
Use the angle =213.75º + 22.50 = 236.25º
The 12th Anchor bolt Coordinates
Use the angle =236.25º + 22.50 = 258.75º
The 13th Anchor bolt Coordinates
Use the angle =258.75º + 22.50 = 281.25º
The 14th Anchor bolt Coordinates
Use the angle =281.25º + 22.50 = 303.75º
The 15th Anchor bolt Coordinates
Use the angle =303.75º + 22.50 = 326.25º
The 16th Anchor bolt Coordinates
Use the angle =326.25º + 22.50 = 348.75º
