Building construction:

Building Construction is an Engineering Science, which deals with the technique of construction of buildings.In Building construction, A building is de­fined as an enclosed space covered by a roof. Buildings in general can be classified into two categories viz. Public Buildings and Resident al Buildings. Public buildings are those which are primarily meant for the use of the general public, such as an office, a school, a college, a hospital, a cinema house, etc , whereas a residential building is only meant either for a single individual or group of individuals, such as an ordinary dwelling house or a bungalow. As far as techniques of construction are concerned, for an engineer both are the same.

In Building construction Every structure has two component parts. One is called; foundation and the other super-structure. Foundation is that part of the structure which is generally constructed below the ground level. It is often confused that foundation is constructed to take up the load of the structure or to support it.

Soils and their Bearing Capacity The soils on which a structure rests may be classified into three categories: (a) Hard soils. These soils are generally rocky in nature, in compressible and can bear fairly good loads. Solid rock, moo rum and stony soils are examples. (b) Soft soils. These are alluvial soils and are compressible when loaded. They can to take much load. Ordinary clay, loam, and common soils are examples of this. (c) Spreading soils. These soils are compressible when they are confined and prevented from spreading. These soils when load­ed spread out laterally. Sand and gravel are examples of this type of soil. Bearing capacity of soils. Bearing power or Bearing capa­city of a soil is defined as the maximum load that a…

The loads coming on the foundations

Loads The loads coming on the foundations are generally divided into (i) Live Load (ii) Dead Load (iii) Wind Load and (iv) Snow load. (i) Live Load: It is a temporary or moving load. The weight of the inhabitants of a building, the weight of furniture or any stored material is called Live Load. Sometimes the live load is also called super-imposed load. For designing foundations, the live load on the structure is also taken into account. (ii) Dead Load: It is the permanent load of the structure, i.e. the weight of the structure itself. The weight of the walls, floors, roofs, weight of fixed machinery and any immovable load, is called dead load. (iii) Wind load: When the wind blows, it causes a lateral thrust or pressure on the vertical as wall as the inclined embers of the structure. This wind pressure is called wind load. The ten decay…

Different types of stairs generally used in public and residential buildings

Learn Types of stairs : Stair, Straight flight stairs.Dog legged stairs.Open newel stairs.Quarter turn stairs.Bifurcated stairs.Geometrical stairs.Spiral stairs. See also Requirement of a good stair case Definitions of technical term used in stair case Types of stairs The following are the different types of stairs generally used in public and residential buildings Straight flight stairs. Dog legged stairs. Open newel stairs. Quarter turn stairs. Bifurcated stairs. Geometrical stairs. Spiral stairs. Straight flight stairs. It is the simplest type of stairs, and con­sists of one or in some cases two flights running in one direction only. These stairs are used, when the space available is narrow and long. Dog legged stairs. It is a very common and popular type of stairs and is used in public as well as residential buildings. It consists of two flights running in opposite directions, separated by a half space landing or a quarter space landing…

Requirement of a good stair case

Requirement of a good stair case A stair should be well ventilated. It should have good approaches from all corners of the building. Every flight should be separated from the other by spacious and well ventilated landings. Each flight should have not more than 12 steps As far as possible winders should be avoided. If at all, they are to be provided, they should be provided at the bottom and not at the top. The width of the landing should not be less than the width of the stairs. The width of the stairs in residential buildings should no be less than 75 cm and for public buildings it should not be less 1han T25 m. The pitch of the stairs should not be more than 25° for making the ascent and descent easy. In order to obtain a satisfactory pitch, the following general rules are used to obtain the…

It is the vertical distance between the two conse­cutive steps. The vertical portion of the step is called Tread. The horizontal portion of the step is called tread. The horizontal distance between the two consecutive risers is called Go, Going or Run. Nosing. It is the front edge of the tread which projects beyond the riser. Fliers.The rectangular steps of uniform shape and size are called Fliers. Winders.The triangular or wedge shaped steps, used for changing the direction are called winders.

FUNCTIONS AND TYPES OF FOUNDATIONS

Learn FUNCTIONS AND TYPES OF FOUNDATIONS,foundation,types of foundation,spread foundation,pile foundation,friction pile,end bearing pile Foundation The lowest part of a structure which transmits the weight of the structure together with live loads, seismic and wind pressure to the ground surface on which the structure rests, ensuring its safe bearing capacity, is called foundation. To increase the stability of the structure, foundations are generally placed below the ground level. Functions of Foundations Following are the main functions of foundations : To transmit and distribute the total load of the struc­ture to a larger area of underlying support. To prevent differential settlement of the structure. To provide stability to the structure. Types of Foundations The following are the main types of foundations : Spread Foundations. The total load of the structure transmitted to the base of the structure is spread over a large area by a spread foundation. The width of the wall…
