  3. Do youknowwhat a wallis and whatisitsfunction?

  4. Is a vertical structure, usually solid, that defines and sometimes protects an area. • A building wall will usually have: • structuralelements • Insulation • surface

  5. Functions of thewalls • containmentanarea • forwalling • delineatesa building • separatesspace in buildings • to support roofs and ceilings

  6. Characteristics • The wall may house various types of electrical wiring or plumbing • Building walls frequently become works of art externally and internally • Curtain walls

  7. Materials Stones Brick Concrete Wood Masonry The two most common materials used nowadays for walling in domestic construction are brickwork and blockwork.

  8. TYPES OF WALLS The two types of walls are load-bearing, which supports the weight of floors and roofs, and non-bearing wall, which at most supports its own weight.

  9. LOAD-BEARING WALL The load-bearing wall of masonry is thickened in proportion to the forces it has to resist: its own load, the load of floors, roofs, persons, etc., and the lateral forces of arches, vaults, wind, etc., that may cause it to crack or buckle. Its thickness can often be reduced at the top, because loads accumulate towards the base.

  10. Doors and windows weaken the resistance of the wall and divert the forces about them to the parts on either side, which must be thickened in proportion to the width of the opening. The number of openings that can be used depends on the strength of the masonry and the stresses in the wall. Walls in light, wood-framed structures and in reinforced-concrete construction may have a bearing function also

  11. The placement of walls is determined by the type of support for floors and roofs. The commonest support is the beam, which must be jointed to walls at both ends. All floors and coverings are most easily supported on straight, parallel walls except the dome.

  12. NON-BEARING WALL A non-bearing wall system is an outer covering of a building in which the outer walls are non-structural, but merely keep the weather out and the occupants in. As it is non-structural it can be made of a lightweight material reducing construction costs. The non-bearing wall appears only where loads are carried by other members.

  13. CONCLUSIONS Walls are vital in architecture and our life, because they give us shelter protecting us from the outside. Some of them are used to bear loads, but others work just as a separation from the outside and at the same time, to give the building best visuals.
