For the analysis and design of structure, the forces are considered as the “Loads” on the structure. In a structure all components which are stationary, like wall, slab etc., exert forces due to gravity, which are called as “Dead Loads”.

**Design
Loads**

For
the analysis and design of structure, the forces are considered as the �Loads�
on the structure. In a structure all components which are stationary, like
wall, slab etc., exert forces due to gravity, which are called as �Dead Loads�.
Moving bodies like furniture, humans etc exert forces due to gravity which are
called as �Live Loads�. Dead loads and live loads are gravity forces which act
vertically down ward. Wind load is basically a horizontal force due to wind
pressure exerted on the structure. Earthquake load is primarily a horizontal
pressure exerted due to movement of the soil on the foundation of a structure.
Vertical earthquake force is about 5% to 10% of horizontal earthquake force.
Fig. 1.3 illustrates the loads that are considered in analysis and design.

IS875
-1987 part 1 gives unit weight of different materials, Part � 2 of this code
describes live load on floors and roof. Wind load to be considered is given in
part 3 of the code. Details of earthquake load to be considered is described in
1893 � 2002 code and combination of loads is given in part 5 of IS875 � 1987.
