INTRODUCTION
Reinforced concrete (RC) buildings often have vertical plate-
like RC walls called Shear Walls in addition to slabs, beams
and columns.
Shear walls are vertical elements of the horiontal force
resisting s!stem. Shear walls are constructed to counter the
effects of lateral load acting on a structure.
RC shear walls provide large strength and stiffness to
buildings in the direction of their orientation, which
significantl! reduces lateral swa! of the building.

CONCLUSIONS
*.;t is seen that stiffness of building is increases with
provision of shear wall in building.
.;t is also seen that natural fre#uenc! of building is increases
with provision of shear wall.&.Stiffness of building is increases up to .*4< b! provision
of shear wall in building
3.2atural fre#uenc! of building increases up to 05< b!
