1. INTRODUCTION
Reinforced concrete shear walls are used in Side column 300mm x600mm
building to resist lateral force due to wind and
earthquakes. They are usually provided between Corner column 500mm x500mm

resisting by transferring the wind or earthquake load Thickness of slab 150 mm
to foundation. Besides, they impart lateral stiffness
to the system and also carry gravity loads. Thickness of Shear wall 230 mm

Shear wall may become imperative from the point of 415
view of economy and control of lateral deflection.
When shear wall are situated in advantageous
positions in the building they can form an efficient

3. MODELLING AND ANALYSIS
Building is modeled using stander package
ETAB. Beams and columns are modeled as two
noded beam elements with six DOF at each node.
Shear wall are modeled using shell element.
Equivalent static analysis or linear static analysis is
performed on models. Based on analysis result
parameters such as bending moment, shear force in
column, displacement, storey drift and storey shear
are compared for each model. The following models
have been considered.
Model I :- Bare frame without shear wall.

Model II :- Dual type structural system with
channel shape of shear wall

Model III :- Dual type structural system with L
shape of shear wall.

Model IV :- Dual type structural system with
rectangular Figure.3 : Model II

Model V :- Dual type structural system with Box

5. CONCLUSION
From above results it is clear that shear wall
frame interaction systems are very effective in
resisting lateral forces induced by earthquake. The
study indicates the significant effect on shear force
and bending moment of column at different levels of
the building by shifting the shear wall location.
Placing shear wall away from center of gravity
resulted in increase in the most of the members
forces. It follows that shear walls should be
coinciding with the centroid of the building. For
