Sinking Foundation | Building Construction

Foundation is the most primary component of the building on which it stands. The life of the building depends on the quality of foundation. For a good and stable foundation, the structural design of the foundation has to be done properly in a systematic way under the guidance of a structural engineer.

If the casting of foundation is not paid attention to and is not laid properly on a stable soil, the structural problems are bound to develop. Every soil has a specific bearing capacity which is very necessary to be checked before designing the foundation. Without the consideration of bearing capacity of soil, the structural design for the foundation may not be suitable for that land.

Cause of Sinking Foundation

Sinking foundation is a problem that occurs in case of improperly laid foundations which is the result of careless consideration of the soil type. The problems are very crucial and have to be solved as soon as they are detected in order to prevent the structure from further damage.

Detecting Foundation problems

People living in areas with unstable soil conditions need to watch out for the signs of foundation problems. Some of the signs could be as follows:

First sign:

The house is gradually slanting to one side. (This is a very prominent example of sinking foundation problem. As soon as you notice this happening, you can immediately conclude it to be related to foundation and take action immediately before the condition of the structure gets worse.)

Introduction to Design of RCC Structures

RCC structures

RCC (Reinforced Cement Concrete) is a construction technology which evolved with the evolution of different structural materials in the 18th century during the Industrial Revolution.

Industrial Revolution brought in new technology which helped in the manufacture of various materials. The Architect Le Corbusier used RCC for various constructions. He believed that any shape and form was possible; if RCC is to be used.

For example, Notre Dame Du Haut, Ronchamp, France

This is an example of Le Corbusier Project where he used RCC like plastic.

What is RCC?

RCC means Reinforced Cement Concrete, i.e., cement concrete reinforced with steel bars, steel plates, steel mesh etc to increase the tension withstanding capacity of the structure.

Cement Concrete can take up immense compression but weak in tension whereas steel is good in withstanding both tension and compression.

Foundation Design

Foundation is the base of any structure. Without a solid foundation, the structure would not hold for long. We have to be very cautious with the design of foundations because our entire structure rests on the foundation. The job of a foundation is to transfer the loads of the building safely to the ground.

The strength of the foundation determines the life of the structure. As we discussed in the earlier article, design of foundation depends on the type of soil, type of structure and its load. Higher the load bearing capacity of the soil, the larger the load it could safely carry.

Foundations are basically divided into Shallow Foundations and Deep Foundations.

In this article, we are going discuss the step by step guide to Column Footing Design for a shallow foundation.
