Types of construction

  1. 1. Vigyan Ashram,Pabal
  2. 2. 1) Wall bearing construction In wall or load bearing construction, all load of roof and structure is carried by walls down to its foundation. This type of construction may not use supporting column or wood pillar.
  3. 3.  The size of walls needs to be bigger to carry all the loads. Further there is limitation to construct long walls at a stretch. This is typically used in residential or 1 -2 storied buildings. This is economical than RCC structure or steel frame structures.
  4. 4. 2) Reinforced cement concrete (RCC) Most of the high rises building uses RCC techniques.
  5. 5. RCC In an RCC framed structure, the load is transferred from a slab to the beams then to the columns and further to lower columns and finally to the foundation which in turn transfers it to the soil. Cement concrete is strong in compressive strength but weak in tensile strength. To increase tensile strength we use mild steel bars in cement concrete. Steel bars used in cement concrete provide good strength to the structure.
  6. 6. A care must be taken that steel should not disturb during concreting. Steel rods should be properly binded and proper planks or plates must be provided for walking. Curing of all concrete is done at least for 20 days. Usually steel bars are rough ened or corrugated to further improve the bond or cohesion between the concrete and steel. Care must be taken that there should be no joints in steel bars used for RCC work. Therefore you might have observed that steel used for RCC work is long in length. If full length steel bars are not available, proper overlap should be given in steel bar and overlap should be staggered. RCC
  7. 7. 3) Peb (Pre Engineered Building)-
  8. 8. In structural engineering, a pre-engineered building (PEB) is designed by a manufacturer to be fabricated using a pre-determined inventory of raw materials and manufacturing methods that can efficiently satisfy a wide range of structural and aesthetic design requirements. Within some geographic industry sectors these buildings are also called Pre-Engineered Metal Buildings (PEMB) or, as is becoming increasingly common due to the reduced amount of pre-engineering involved in custom computer-aided designs, simply Engineered Metal Buildings (EMB).
