parts, building
Introduction The chief purpose of building construction is to provide walls and roofs for shelter and floors to carry the occupants and their furniture. If the building has only one storey, it is possible to support the fleuron the ground, but if the building has more than one storey, it necessary to use beams for supporting the floor. Beams are parallel horizontal members supporting the building. A building has two main parts: the substructure, or part below the ground, and the superstructure, or part above the ground. The substructure is usually called the foundation; it includes the basement walls of the building. The superstructure is divided indifferent parts, such as the walls, beams, columns, trusses and arches. The superstructure and the substructure help to support the weight, or load of the building. The dead load of a building is to total weight of all its parts. The live load is the weight of the furniture, equipment and occupants of a building. The construction of a house is performed in the following way: first the excavation is dug for the basement, then the foundation. Walls are constructed below ground level then the framework is raised. The framework is covered with different finishing materials and protected by several layers of paints. The part upon which to liability of the structure depends is the framework. Its function is stand in place and carry the loads. The floors, walls, roofs and other parts of the construction must be correctly designed and proportioned. Designers and architects must determine the size of the walls, the floor joists, the beams and the parts which make up the framework.
