The different types of loads coming on the foundation of a structure are described below-
1. Dead Load
2. Live Load
3. Wind Load
4. Snow Load
5. Earthquake Load
6. Erection load
1. DEAD LOAD
Dead load comprises of the weight of all walls, partitions, floors, and roof including all other permanent construction in the building.
2. LIVE LOAD
Live load consist of moving or variable loads due to people or occupants, their furniture, temporary stores, machineries.
3. WIND LOAD
It is considered as basic wind pressure which is equivalent static pressure in the direction of the wind.
Wind Pressure = kV2
Where k= co-efficient 0.006
V= wind velocity
Wind pressure always acts in the vertically exposed surface of the walls and columns.
4. SNOW LOAD
Actual load due to snow depends upon the shape of the roof and its capacity to retain the snow. The load due to snow may be assumed to be 2.5kg/m3 per cm depth of snow.
5. EARTHQUAKE LOAD
An earthquake load produced waves in every possible direction below ground. As per intensity or scale of earthquake, jerk and shocks are acting on the earth. As per the location of the building in the prescribed zone of earthquake coefficients of earthquake loads are decided.
6. ERECTION LOAD
All loads required to be carried by the structure or any part of it due to storage or positioning of construction material and erection equipment including all loads due to operation of such equipment shall be considered as erection load.
