Examples are the reinforced-concrete wall or vertical truss.
Lateral forces caused by earthquake, wind, and uneven settlement loads, in addition to the weight of structure and occupants; generate powerful twisting (torsional) forces.
These forces can factually tear (shear) a building apart. Reinforcing a frame by attaching or placing a rigid wall inside it maintains the shape of the frame and avoids rotation at the joints.
Shear walls are particularly important in high-rise buildings subject to lateral wind and seismic forces.
SHEAR WALL CONSTRUCTION
Shear
wall, in building construction, a rigid vertical diaphragm capable of
transferring lateral forces from floors, exterior walls, and roofs to the
ground foundation in a direction parallel to their planes.
