As we all know about the disastrous effect of earthquake in past decade, it is important to consider the
effect of seismic (earthquake) loads while constructing any medium or high rise building. Hence to reduce this
adverse effect of earthquake loads on building and to increase the stability, shear walls are provided. Shear walls are
structural members that provide stability and resistance to the structure subjected to lateral forces generally wind and
seismic loads, especially in high rise buildings. They provide adequate strength and stiffness to the whole lateral
displacement of the structure due to laterally subjected loads. These structural members can be constructed from
reinforced concrete, timber/plywood and also from unreinforced masonry. They can be external or internal walls
around lift shafts or stairs and sometimes both. Shear walls have proved to be very successful in resisting strong
earthquake loads so far. In this paper we have aimed to study the effect of providing shear walls on stability and
deflection in 5 and 10 storey building frames and comparing it with the same building frames without shear walls
subjected to lateral forces. We have compared the same building frames in V earthquake zone. A 3-D analysis of
shear wall structures has been carried out using the STAAD.pro v8i software and results are presented.
