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!
