What Is Shear Walls ?

Shear wall is a structural member used to resist lateral forces i.e. parallel to the plane of the wall. 
For slender walls where the bending deformation is more, Shear wall resists the loads due to Cantilever Action. 
In other words, Shear walls are vertical elements of the horizontal force resisting system.

Shear walls are especially important in high-rise buildings subject to lateral wind and seismic forces. 

Generally, shear walls are either plane or flanged in section, while core walls consist of channel sections. They also provide adequate strength and stiffness to control lateral displacements.
The shape and plan position of the shear wall influences the behavior of the structure considerably. 
Structurally, the best position for the shear walls is in the center of each half of the building. 
This is rarely practical, since it also utilizes the space a lot, so they are positioned at the ends.
