III. Read and translate the text. Floors

Floors are the structural elements which divide a building into stories and carry the dead load or the weight of the floor itself and the superimposed or live load. According to the design they are classified as basement floors, upper floors, and attic floors. But all of them must satisfy some common requirements: sufficient strength and rigidity, good sound insulation, fire resistance. It is obvious that basement and attic floors must be warmed while the floors in sanitary units must be water and gas resistant. As to the materials used floors are divided into three groups: timber, reinforced concrete floors and floors laid along steel beams.

Timber floors are simple to erect but they are liable to fire, to rot and are not so durable as others. Therefore they are generally used in dwellings and service buildings.

Reinforced concrete floors have many advantages which allow to use them especially in big constructions of industrial design. Reinforced concrete floors are not liable to fire, they are strong, durable and economical. Precast reinforced concrete floors developed by Russian designers meet the requirements of high speed industrial construction. Most widely used monolithic floors are ribbed and beamless. Floors laid along steel beams are usually made with fireproof cladding in precast or monolithic reinforced concrete slabs. There are also combined precast-monolithic floors and many other kinds besides the three main groups mentioned.
