Foundations

A building has two main parts, the substructure (the part below ground) and the superstructure (the part above ground). The substructure is usually called the foundation and includes the basement walls even though these may extend above the ground.

Both the substructure and superstructure help to support the load (weight) of the building. The dead load of a building is the total weight of all its parts. The live load is the weight of the furniture, equipment, stored material, and occupants of a building. In some regions, the wind load of a building is important if the structure is to withstand storms. The snow load may also be an important factor. In some areas, buildings have to be constructed to withstand earthquake shocks.

The purpose of foundation is to carry the load of structure and spread it over a greater area, evenly and without undue settlement, to the ground beneath. They carry both dead and live loads. There are three main types of foundations: (1) spread, (2) pier, and (3) pile.

Spread foundations are long slabs of reinforced concrete that extend beyond the outer edges of the building. Such foundations are not as firm as those based on solid rock. The footing areas in contact with the soil must be of sufficient size to spread the load safely over the soil and to avoid excessive or uneven settlement. Any such settlement would cause walls to crack or doors to bind.

Pier foundations are heavy columns of concrete that go down through the loose topsoil to a bed of firm rock. This bed may also be sand, gravel, or firm clay. If the bed consists of firm clay, the pier is usually enlarged at the base, to increase the bearing area.

Pile foundations are long, slender columns of steel, concrete, or wood. Machines called pile drivers hammer them down as deep as 60 meters to a layer of solid soil or rock. Workers can tell when the columns reach their proper depth by the number of blows. The pile driver needs to drive the columns a few centimeters deeper. These columns transmit the building load to the supporting soil.

The importance of pile foundations in building and industrial construction as well as in civil engineering has increased considerably over recent years. The piles transmit the loads of the structure to deep-lying, load bearing strata of the subsoil. Today’s modern, large structures force the civil engineer to develop advanced methods and techniques in order to make sure that the ever increasing and highly concentrated loads are safely transferred to the subsoil without causing settlements.

The significance of pile foundations is reflected in the large number of pile systems currently available on the market. Depending on the method of production, piles can be divided into two main types: cast in-situ concrete piles and prefabricated piles.

Cast in-situ piles are mostly bored piles while precast piles or prefabricated piles are driven.

Beams, girders, and columns support a building much like bones support the body. They form the skeleton of the superstructure and bear the weight of the walls and each floor of the building. Beams and girders run horizontally. Girders are usually larger than beams. Closely spaced beams are called joists, especially in wooden buildings. Purlins are small beams that brace ratters or girders and help provide the structure to support roofs. Beams above window and door openings are called lintels. Slabs are beams whose width is greater than their depth.

Columns are heavy vertical supports that carry the load of beams and girders. Trusses consist of many wood or steel supports that are connected in triangular patterns. They provide the strength and rigidity to span large distances with relatively small amounts of material. Arches are curved supports that usually extend over openings.
