TEXT: TYPES OF BUILDINGS

Buildings are divided into classes according to their construction and use. As to the construction they are classified as:

- frame construction;

- non-fireproof construction (ordinary and slow-burning);

- fireproof construction.

Frame construction embraces all buildings with exterior wooden walls or covered with sheet metal. Such buildings have floors and partitions of wood and are considered the most inflammable type of construction.

Non-fireproof construction includes all buildings with exterior walls of masonry but with wood floor construction and partitions. Slow-burning construction has heavy timber fire resistant framing.

Fireproof construction includes all buildings constructed of incombustible material with floors of iron, steel or reinforced concrete beams. Wood may be used only for upper floors, windows and doors. In buildings of great height the flooring must be of incombustible material and all structural elements should be surrounded with fireproof material to protect the structure from the effect of heat.

7.К какому из перечисленных типов конструкций можно отнести следующие здания.

- A building with floors of reinforced concrete and all structural elements surrounded with fireproof material.

- A building with exterior wooden walls and partitions of wood.

- A building with heavy timber framing and exterior walls of masonry.
