The Pole Barn Post Size Calculator is a crucial tool in the realm of construction planning, specifically tailored for pole barn structures. Its primary function is to determine the appropriate size of posts required to support the weight and load of a pole barn, ensuring structural integrity and safety.
Formula of Pole Barn Post Size Calculator
The calculation performed by the Pole Barn Post Size Calculator is based on a simple yet fundamental formula:
Post Size (in square inches) = (Total Load on Post) / (Allowable Soil Bearing Capacity * Post Spacing)
Where:
- Post Size represents the cross-sectional area of the post required, typically measured in square inches.
- Total Load on Post encompasses the combined weight that each post must bear, including the load of the roof, walls, snow, and any additional loads.
- Allowable Soil Bearing Capacity denotes the maximum load per unit area that the soil can support without experiencing excessive settlement, usually expressed in pounds per square foot (psf).
- Post Spacing indicates the distance between each post, typically measured in feet.
General Terms and Conversions
To facilitate user understanding and streamline the process, here’s a table outlining general terms commonly associated with pole barn construction:
| Term | Definition |
|---|---|
| Pole Barn | A type of structure characterized by its roof supported by poles or posts. |
| Soil Bearing Capacity | The maximum load that soil can support without experiencing excessive settlement. |
| Cross-Sectional Area | The area of a shape as if it were cut through at a particular point. |
| Total Load | The combined weight that a post must support. |
| Post Spacing | The distance between each post in a structure. |
Example of Pole Barn Post Size Calculator
Let’s consider an example to illustrate the practical application of the Pole Barn Post Size Calculator:
Suppose we’re constructing a pole barn with a total load on each post of 10,000 lbs. The allowable soil bearing capacity is 1500 psf, and the post spacing is 8 feet. Using the calculator’s formula, we can determine the required post size as follows:
Post Size = 10,000 / (1500 * 8) = 0.833 square feet
This calculation informs us that each post should have a cross-sectional area of approximately 0.833 square feet to adequately support the specified load.
Most Common FAQs
A: To calculate the total load, you need to consider the weight of the roof, walls, any anticipated snow load, and any additional loads the structure may bear. Summing up these factors will give you the total load per post.
A: It’s essential to determine the soil bearing capacity of your construction site beforehand. You may consult a soil engineer or refer to geological surveys of the area to obtain this information accurately.
A: While the Pole Barn Post Size Calculator is specifically designed for pole barns, the underlying principles of load calculation and structural support apply to various construction projects. However, it’s advisable to use specialized calculators or consult with professionals for different types of structures.
