The foundation has an important role to play in enhancing the strength of the building. It provides the necessary support that is required by any architectural structure. It allows the weight of the structure to the ground with sufficient bearing capacity for the structure to remain intact with the ground without falling off.
Typically, there are two types of foundations on which an architectural structure is hosted. These types of foundations can be categorized as:
- Shallow Foundation- It is placed where the soil has all the necessary bearing capacity for the structure to remain intact with the ground.
- Deep Foundation- It is required where the soil doesn't have the adequate strength or bearing capacity to support the structure's load.
Hence, the foundation is required to penetrate the ground more profound enough to get the essential bearing capacity.
As for the strip footing or Strip Foundation, it can be categorized within the shallow foundation. But what exactly is a strip foundation, and how does it work? If you are bombarded with these questions, you are at the right place. In this article, you can find everything you need about strip footing or foundation. So, keep reading this article to learn more about strip footing.
What is Strip Footing?
As mentioned earlier, strip footing is a shallow foundation that hosts load-bearing walls and other architectural structures. Mostly this continuous strip form provides the necessary support and strengths to a wall and acts as a base for the wall. Strip footing is also known as wall footing, spread footing, and continuous footing.
How Does it Work?
It provides the necessary support for the structure to remain intact with the ground for a long time. As for the width of the strip, it must be three times the width of the wall. The necessity of the strip is to spread the weight of the architectural structure evenly throughout the subsoil that possesses the capability to support the load without any inconveniences.
In simple terms, the soil should possess the essential bearing capacity for keeping the structure intact. Or the structure might collapse from the intense load that the structure itself would create.
The concept of the strip foundation is that the structure's weight is evenly distributed through the base to the soil at precisely 45 degrees. Furthermore, the depth of the foundation should also be precisely equal to or greater than the width of the structure.
To create Strip Footing, you can use either concrete or bricks. However, one of the most commonly used materials is concrete for the endurance quality it offers.
Where Should Strip Footing be Used?
- Typically, Strip Foundation is used to build foundation support for the load-bearing walls.
- To build Strip Foundation, the Soil should have the bearing capacity.
- You can also build Strip Foundation in soil with little bearing capacity. But you will have to build a broader footing with reinforced concrete.
When Should Strip Footing not be Used?
- When the soil quality is not appropriate to support a shallow foundation.
- If the architectural structure is 3 or 4 stories high, you should opt for a deep foundation instead of strip Footing.
- It would be best if you also avoided stripping the foundation of the structure you are building an architectural structure with a heavy load.
Conclusion
Strip footing is extremely simple in design and doesn't require too many tools or equipment to build. However, like any foundation, strip footing also comes with a few complications and disadvantages. Hence, it would be best if you wisely choose where you want to put this foundation.
