Basic Detail Of Foundation | Different Elements Of Building |

-

Foundation:- The lowest part of building, which located below the ground level and which transmit the loads of the structure to the ground are known as Foundations. 

Types of Foundation:-  

 Foundation may be broadly classified into two categories -
     1. Shallow foundation
     2. Deep foundation

Shallow foundation:- Shallow foundation are made by making open excavation.
In shallow foundation 
                                          D ＜ B      
 Where 
     D = Depth of foundation
     B = Width of foundation



1. Isolated/Column footing
2. Wall footing
3. Continuous footing
4. Inverted arch footing
5. Spread footing
6. Raft or mat foundation
7. Combined footing
8. Strap or cantilever footing
9. Grillage footing




Deep foundation:- Deep foundations are foundations which transmit the load of the structure of strong soil beds or rock beds available at great depth.
In deep foundation  
                                          D ≥ B      
 Where 
     D = Depth of foundation
     B = Width of foundation


1. Pile foundation
    a. Bearing pile foundation
    b. Friction pile foundation
2. Caisson/Well foundation
3. Pier foundation





Different element of building:- Element of buildings are classified into two following groups -
1. Substructure 
2. superstructure

 Elements in -
 Substructure:-    
1. Foundation
2. Footing
3. Plinth
 Superstructure:- 
1. Walls           4. Roof            7. Stairs                  2. Doors          5. Floor           8. Slab  
3. Window     6. Ventilators

LONG WALL & SHORT WALL METHOD

-
Image
Long Wall &Short Wall or 'Out-to-Out and In-to-In' Method In this method, the longer walls in a building are taken as long walls & calculated from out-to-out & the partition or shorter walls which make the right angle with the long walls are taken as short walls and are calculated from in-to-in for a particular layer of work. To calculate the quantities multiplying the lengths of long & short walls by the breadth & the height of wall. These lengths of long and short walls differ in each layer of footing. PROCEDURE:- 1. Prepare the foundation plan shown in fig. with all dimensions. Centre-to-Centre dimensions are taken out by adding half width of each cross wall to inner dimension of room. 2. Now divide the walls into two groups. In plan, walls in the horizontal direction are called Long walls & vertical direction walls are called Short walls & Vice-Versa. 3. Measure the length of long wall for an item by using formula- Length ...
