Why is the foundation of a building made broader?

Pressure is inversely proportional to area of the surface. Hence greater the area, lesser the pressure. For the building to exert less pressure on the ground and not sink into the earth, the foundation of the building should have a wider area.

Why are building foundations wider than walls?

Answer:The foundation of the buildings is made wider than the walls in order to decrease the pressure of the building at its base and prevent the building from sinking. Explanation: The wider foundation has more surface area which helps to decrease the pressure .

How is the foundation of a building made?

A foundation is a lower portion of building structure that transfers its gravity loads to the earth. To make a foundation, we normally dig a trench in the ground, digging deeper and deeper until we come to subsoil, which is more solid than the topsoil that is used to grow plants and crops.

Why is the base of a dam or a high rise building made wider?

The base of a dam or a high rise buildings made wider because the pressure exerted by a liquid increases with depth,as the depth increases more and more pressure is exerted on the base of dam or a high rise buildings.

Why do the building foundations have a large horizontal area of contact with the ground?

Building foundations have a large horizontal area of contact with the ground . This would reduce the pressure being exerted to be smaller and thus make the building more stable (prevent the entire structure from sinking).

What is the main purpose of a foundation?

Foundations provide the structure’s stability from the ground: To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement).

What is the purpose of foundation in a structure?

A foundation sits between the building and the ground, making it the lowest part of the structure. It distributes loads from the house to the soil, and it is integral that it is strong enough to withstand the entire weight of the building.

Why is the base size of most structures wider than the top of the structure?

However, the base is typically much wider than the top to support the weight of the building and its contents, not to mention the wind sheer on the structure. Building construction methods are such that the dimensions at the top of the building are the same as at ground level.

Why buildings are built with wider basement?

Answer: the reason of constructing building in wider basements is to make sure the foundation of the tall buildings are strong, they are built with a broader basement. So, if the area in the bottom is higher, the pressure exerted by the buildings on the ground would be less and so building will not sink in ground .

What is the reason that the foundation distribute the weight of structure over a large area?

What does foundation mean in construction?

The foundation of any building serves two main purposes — distribute the weight from load-bearing walls to the soil or bedrock beneath and keep groundwater or soil moisture out.

What is the importance of foundation in building construction?

The stronger is the foundation, more stable is the structure. The proper design and construction of foundations provide a proper surface for the development of the substructure in a proper level and over a firm bed. Specially designed foundation helps in avoiding the lateral movements of the supporting material.

What are the different types of foundations in buildings?

Read our introduction to foundations if you have missed it. In this article we will discuss the common types of foundations in buildings. Broadly speaking, all foundations are divided into two categories: shallow foundations and deep foundations. The words shallow and deep refer to the depth of soil in which the foundation is made.

What is the importance of deep foundation?

The deep foundation transfers the load to a deeper depth below the ground surface. A tall building like a skyscraper or a building constructed on very weak soil requires deep foundation. If the constructed building has the plan to extend vertically in future, then a deep foundation must be suggested.

Why are combined foundations better than pad foundations?

The presence of roads, and other buildings in the vicinity of the building site – the walls of the adjacent building and the roads can restrict the area that needs to be excavated, making combined foundations preferable over isolated pad foundations.
