LOADS :à External forces and moments (or couples) acting on a body are called loads.

 

TYPES OF LOADS ON A STRUCTURE

ü These are loads to be considered in the design of a structure.

·     Dead loads

·     live loads

·     wind loads

·     snow loads

·     seismic loads/Earth quake loads

 

Ø Dead loads  :à The self weight of building (weight of wall, column, floors, roofs etc.) are dead loads. These are permanent loads acting on a structure.

 

 

Ø live loads  :à The moving or movable loads on a building like people, furniture’s, etc. are the live loads. These loads keep on changing time to time.

 

Ø wind loads  :à The wind load act horizontally on the surface of walls, roofs caused by the movement of air relative to earth. Wind load depends on several factors like height of structure, geographic location of structure.

 

Ø seismic loads/Earthquake loads    :à The loads are internal force which acts on the structure due to the earthquake develop group movements. These loads are also called seismic loads.

 

Ø snow loads  :à The loads caused by snow on a structure are snow loads. Snow loads are only considered in snow fall areas.
