Observe the past records of earthquake, there’s increase within the demand of Earthquake resisting

building which might be consumed by providing shear wall systems with in the building positioning of shear

wall has influence on the overall behaviour of the building. A (G+10) Storey building is taken under

consideration. RCC building are used with different position of shear wall.Positioning of shear wall has

influence on the general behaviour of the building for effective and economic performance of building it’s

essential to position shear enclose a perfect location. Three completely different cases of the shear wall

position for a building are analysed.This paper presents the response of building with different positioning of

shear wall using response spectrum analysis method.The parameters like Nodal displacement,Beam

displacement,Maximum displacement,Combination stress and base shear, Axial force has studied and

suitable location of shear wall has determined among these models. The whole analysis is done on

STAAD.PRO V8i.

I. INTRODUCTION

1.1 GENERAL: Earthquake has always been a Earthquake has

always been a threat to human civilizationfrom the

day of its existence, devastating human lives,

property and man-made structures. Therefore the

continuous research works are going on around

the world, revolving around for the development of

new and better techniques that can be

incorporated in structures for better seismic

performance. Obviously, buildings designed with

special techniques to resist damages during

seismic activity have much higher cost of

construction than normal buildings, but for safety

against failures under seismic forces it is a

prerequisite.

There are many different methods of seismic

analysis like time history method, response

spectrum method seismic coefficient method etc.A

study has been carried out to determine the

strength of RC shear wallof a multistoried building

by changing shear wall location. The shear wall has

positioning different locations of building those are

Model of building without shear wall (Model 1)

Model of building shear wall at center (Model 2)

Model of building shear wall at corners (Model 3)

Model of building shear wall at core (Model 4)

1.2 FUNCTIONS OF SHEAR WALL:

The main functions of shear wall can be described

as follows:

Providing Lateral strength to the Building:

shear wall must provided lateral shear strength to

the building to resist the horizontal earthquake

forces, wind forces and transfer these forces to the

foundations.

Providing lateral stiffness to the Building: shear

wall provide large stiffness to building in the

direction of their orientation, which reduce lateral

sway of the building and thus reduce damage to

structure

1.3 OBJECTIVES OF WORK:

To judge the effect of an R.C. shear walls on

structures when provided at different

locations.

To study the results of maximum

displacement, displacement,base shear, beam

displacement, combination stress and Nodal

displacement, for four different models.

To understand the purpose of using shears

walls using STAAD.pro. Through this work

II. LITERATURE REVIEW

Abhinav (2016) Analysed 11-storey RCC building

with shear walls using STAAD Pro software. The

location of shear walls was main objective. The

present study concluded that shear wall along the

periphery is much more efficient than other

models.

Priyanka Soni (2016) Have analysed multi-storey

building of different shear wall locations and

heights using STAAD Pro software. The three

building models viz., G+10, G+20 and G=26 were

taken into consideration for comparative study. It

has been concluded that shear wall at middle is

most preferable.

Varsha R.Harne (2014) performed comparative

study of strength of RC shear wall at different

locations on multistory building.The main focus of

this papers is to determine the solution of Shear

wall location in multistory building. A six storey

building in zone 2 is considered. Three different

case of Shear wall position for a six storey building

have been analyzed. Lateral deflection for building

having shear wall at outer edges was reduced as

compared to other models.

Rahangdale.M (2013) conducted study on G+ 5

storey symmetric building in Zone IV was

presented with some preliminary investigation

which was analyzed by changing various positions

of shear wall with different shapes and found that a

box type shear wall at centre is more safer than to

other type of walls placed at different locations.

V. CONCLUSIONS

In this Study ,The analysis of multistoried

buildings are done by STAADPRO software using

Response spectrum analysis and we have got the

following conclusions.

1. 1.Minimum lateral displacement of the

building has been reduced due to the

presence of shear wall placed at corners

Model 3 compared to other models

2. This study is carried out the among all

models as follows

The Maximum displacement of the

structure with shear Wall at edge's is 25%

and 77% less when compared with

maximum displacement of structure

Respectively.

The Nodal displacement of the structure

with shear wall at edge's is 53% and 77 %

less when compared with nodal

displacement of structure without shear

wall in x and y directions Respectively.

The base shear of the structure with shear

wall at edge's is 86% less when compared

with base shear structure without shear

wall in x- direction respectively

The axial force of the structure with shear

wall at edge's is 38% less when compared

with axial force of structure without shear

wall in x-direction respectively

The combination stress of the structure

with shear wall at edge's is 51% less when

compared with combination stress of

structure without shear wall in x-direction

respectively

The beam displacement of the structure

with shear wall at edge's is 53% and 77%

less when compared with beam

displacement of structure without shear

wall in x and y directions Respectively

3. Structure can be compared and design

easily by using STAAD PRO and can be

used to analysis the structure for strength

point of view.

Therefor the overall conclusion is positioning of

shear wall at corners results is in effective and

efficient performance of during earthquake among

the four models studied here Model 3 having shear

wall along the four corner displayed better results

compared to other models.

SCOPE FOR FUTURE WORK

In this study only Response spectrum method

was performed so there is scope to perform

Time history analysis and Equivalent static

method etc…

As analysis is carried out for only G+10

Building it can be extended to high raise

buildings.

The present study is carried out on the building

provided with limited positioning of shear wall.

Further study can be carried out by providing

opening and other different positioning of shear

wall in building.

This analysis is carried out by using ETABS

software etc…
