Abstract - Nowadays shear wall as structural element in
high rise buildings has become a common practice. It has
become the most common way to form the Lateral load
resisting system in High rise structures. Veryhighstrengthand
stiffness of the shear walls can be used to resist large
horizontal loads and supporting Gravity loads. This makes
them advantageous in many structuralapplications. Themain
focus of this project is to determine the most suitable location
or position for the shear wall. A G+10 RCC building subjected
to earthquake loading located in zone IV is considered in this
project. The equivalent Lateral force method or static method
is used to calculate the Earthquake load using IS1893 (Part
I):2002. Analyses were performed on ETABS. This research
focuses on determining strength of shear walls in different
locations. We have tried to place shear walls at different
locations and an attempt has been made to check the best
position for shear walls in a building. Six different cases of
shear wall position for a G+10 building have been analyzed.
This project aims to analyze the response of structure using by
static method.
Key Words: Shear wall, ETABS
1. INTRODUCTION
Earthquake in general has long devastating history in the
past. Earthquakes are most distressing and a threat to
human civilization, devastating man-made structures, and
human lives. It is such an unpredictable calamity that
survival must ensure the strength of the structures against
seismic forces(13). Therefore, a lot of research works are
going on around the globe for the development of better
techniques that can be incorporated into structures for
better resistance against earthquakes (13). A shear wall is a
structural component located in a building right from
foundation level to top parapet level at various locations.
Shear walls are used to defend against lateral forces.
Structural members which are used to resist lateral forces
due to earthquakes and wind are the Shear walls.
There are manydifferentmethodsofseismicanalysislikethe
time history method, response spectrum method seismic
coefficient method, etc. (13). A study has been carried out to
determine the best possible orientation of the RC shear wall
of a multistoried building by trying out different possible
orientations. And parameters like storey drift, base shear,
nodal displacement are observed and compared.
The six different types of models are as follows (Fig:4-9 )
1. Without a Shear wall
2. Shear wall at the Centre – For Lift cores only
3. Shear walls at Periphery
4. Shear walls at Corners
5. Shear wall along both Longitudinal faces & Lift
cores
6. Shear wall along with both Lateral faces & Liftcores
1.1 Concept
In this project, different position of shear wall is
given. Shear wall gives more stability to the building’s than
normal wall. This building is located in Delhi, zone IV. This
project give idea about shear wall location. This is also show
that the behavior of shear wall in the buildings at different
location. This project gives idea about displacement, drift,
shear.
The location of the shear walls depends on the plan of
structure,core location,thesymmetryofthebuilding,andthe
lateral force experiencedbythestructure.Mostly,shearwalls
should be placed around the outer walls of the building in a
symmetrical form. It isusuallyverydifficulttofindasuitable
location forthe shearwallinthestructure.However,theideal
place is the center of the building. Sometimes, structural
analysis is performed to identify the ideal location in the
structure.
1.3 Properties of shear wall
Shear wall is a structural member positioned at different
places in a building from foundation level to top parapet
level, used to resist lateral forces i.e parallel to the plane of
the wall. There are different materials by which shear wall
can be constructed, but reinforced concrete (RC) buildings
often have vertical plate-like Reinforced concrete walls
(Figure 1) in addition to slabs, beams and columns. Their
thickness can be as low as 150mm, or as high as 400mm in

high rise buildings. Shear walls are usually provided along
both length and width of buildings.

1.4 Functions of Shear Walls
Shear walls must providethenecessarylateralstrengthto
resist horizontal earthquake forces. When shear walls are
strong enough, they will transfer these horizontal forces to
the next element in the load path below them (13). These
other components in the load path may be other shear walls,
floors, foundation walls, slabs or footings.

4. RESULTS
All the six models were analyzed, and the results were
generated from ETABS. Before running the analysis, the
model has been checked for any warnings.
Storey displacements plotted when Earthquake hits in X
direction. Significant storey displacements are observed.
Fig -4: Model case 1
Model 1 having No shear walls tend to show very large
displacements. Very small displacements are observed in
Model 5 (Shear walls at corners). Model 2 & 4 are showing
almost same storey displacements in Y direction. Similarly,
Model 3 & 6. This shows that the contribution of the shear
wall along X – direction is very less.
The max storey displacement is observed to be significantly
reduced when compared with the building without shear
wall. More than 50% reductionindisplacementswasnoticed
just by providing shear walls at the lift cores. Maximum of
about 90% reduction in displacement was observed when
the shear walls were located at the corners of the building.
Different orientations of shear wall have been studied and
the respective reduction was noted and can be seen in the
bar graph. Although we have got 90% reduction with one of
the orientations, we need to check whether it is optimum/
economical or not? To know that I have calculated the
efficiency of every model considered. The efficiency was
calculated by Max storey displacement divided bythelength
of shear wall provided. Calculations showthatthemaximum
efficiency is shown by thr model with the shear walls at the
Lift cores only
Fig -10: Storey displacement in x-direction

Model 1 give more displacement as compared to other
Model, because the model doesn’t have shear walls. Model 5
give very less displacement, because shear walls are
provided at the corners. This configurationisrestrainingthe
displacement in all directionsmakingthestructureverystiff.
The displacements are reduced by almost 50% just by
providing shear walls at the lift cores.
Whereas providing shear walls along longer side of the
structure is observed to be not very efficient. The reason is
quiet obvious that the Moment of Inertia and so the stiffness
of the structure is already higher along longer side,
providing shear walls along this direction may be of no use
and only increasing the cost of the structure.
Fig -11: Storey displacement in y-direction
Fig -12: Maximum storey displacement
In figure 13, reduction of storey displacement with respect
to Model 1 is given. Model 5 has shown the maximum about
90% reduction when shear wall is provided at the corners.
Reduction in displacement may be a fascinating number but
a good structural design can be identified by the efficiencyof
the structural components we are providing. And hence
plotting the efficiency of each and every configuration
considered is very important.

4. CONCLUSIONS
Shear wall is become an important structural component
when it comes to High-rise buildings. Provision of shear
walls in high-rise structures significantly reduce the
displacements and suppress the effect of seismic forces too.
But, just providing the shear walls is not enough. The
location where shear walls have to be provided and the
configuration is of importance. As a structural engineer, we
should always try to make the designssuchthatweareusing
lowest possible quantity of concrete and steel in the
structure. Not only that but utilizing their strengths and
capacities to the fullest.

1. Displacements of the structure can be reduced by
around 50% just by providing shear wall at the
center of the building.
2. Providing shear walls at the corner can be the best
option when it is not possible toprovideshear walls
at the center.
3. Shear wall shall be provided along the shorter edge
of the structure.
4. Providing shear walls along longer side of the
structure may not be useful as structurealreadyhas
higher stiffness along longer direction.
