ABSTRACT
Construction work in India is one of the most widespread activities, involving a range of people from
the small builder in villages and towns to large private companies, public undertakings and various
state agencies.
At present civil engineering has suffered from a drastic evolvement over last decades there has been
a large amount of improvement in civil works management done by many leading company by
hiring structural engineers as a result there is a many structure design and analysis related software’s
are also used by structure engineers, which simplify the design problems and gives the idea about
actual structure how looks and works.
The construction industry requires high degree management of men & material to complete the
project successfully at an optimum cost. Hence a special branch of structural engineering has been
developed to accommodate the designs and analysis of structures which are adopted to improve the
performance of various aspects of an engineering project and optimize the cost.
Government has Expertise in providing modern infrastructure to public and also dealing with
numbers of big projects to secure a good position of India in Global Developed Market in
Infrastructure.
The projects focus on parametric study of cable stayed bridge. Different parameters like side span,
pylon shape, cable stay arrangements etc. affects on the bridge designing specially. Using the
different software’s available in the market for bridge designing it is possible. We were been going
to use MIDAS CIVIL software for our designing and analysis purpose.

1.1 INTRODUCTION
All the Three human basic needs: shelter, food and clothing call for civil engineering construction
works and their subsequent maintenanace.Ordinarily construction activity accounts for 15% of all the
jobs. The construction industry requires high degree management of men & material to complete the project successfully at an optimum cost. Hence a special branch of building construction has been
developed to accommodate the techniques which are adopted to improve the performance of various
aspects of an engineering project.
The branch of structural engineering aims to design and analyse the structure as per the requirement
of site conditions. This branch is of immense importance because if design is wrong or if any factors
which will affect the structure would be not considered then it will be cost to the whole project.
At present construction work in India is one of the most widespread activities, involving a range of
people from the small builder in villages and towns to large private companies , public undertakings
and various state agencies.
Now a days structure designing becomes prime requirement for that purpose many software’s are
available i.e. MIDAS,STADD,ETAB etc.
The construction industry is a major economic activity in India. Construction activities contribute
annually about 10% to the Gross National Product (GDP), Thus Playing a major Role in the
development of the national economy.
The need for professionalism in designing and analysis of structure assumes special significance in
order to ensure that the huge resources invested in the construction industry are deployed efficiently
for the benefit of society and structure operates efficiently.

What is a Bridge?
• “A bridge is a structure built to span physical obstacles such as a body of
water, valley, or road, for the purpose of providing passage over the obstacle.”
• There are many different designs that all serve unique purposes and apply to different
situations.
•
Designs of bridges vary depending on the function of the bridge, the nature of
the terrain where the bridge is constructed and anchored, the material used to make it,
and the funds available to build it.
Type Of Bridges
• Bridges can be categorized in several different ways. Common categories include the
type of structural elements used, by what they carry, whether they are fixed or
movable, and by the materials used.
Based On Structure Type
•
Beam Bridge
• Truss Bridge
• Cantilever Bridge
• Arch Bridge
• Tied Arch ridge
•
Suspension Bridge
• Cable-Stayed Bridge

1.2 STUDY AREA
The projects focus on Parametric study of Cable Stayed Bridge Bridge by taking real life
example Worli Sea Link Cable Stayed Bridge.
Why Bridge Is Required ?
In city like Mumbai where trains also travels full of the people then no concern to talk about
traffic problem.
In Mumbai to travel from Bandra To Worli it takes 60-90 minutes.
To reduce this travel time one of the alternative is to construct the over bridge but due to
nearby two airports in the Bandra there is a no option to construct over bridge so that
government carried out steps to construct the bridge through the sea to connect Bandra and
Worli.
Bandra Worli Sea Link reduces the road length and hence time travel between Bandra andWorli.

2.1 LITERATURE REVIEW
For the Cable stayed bridge researchers analyzed different parameters which would designer
have to keep in mind:
1) Bridge Deck Property
2) Pylon Shape During EQ(A, H, Portal Frame, Spread Pylon & Pyramid Shapes)
The Pylon Shape Has great influence in the mitigation of SSI effects the result showed that in
comparison to rotational A or H shape of pylon diamond shape of pylon is giving less
response. Hence if it is used practically will be proved less economical.
The Inverted Y design of the pylon is a solution that uses the tensioning mechanism and it
provides compromise between deck sizing and costly strengthening methods.
3) C/S of Cable
4) Cable Layout Pattern
The deflection of deck is slightly depend on the layout of cable system either Harp or Fan
system.
The B.M. in the deck using the fan system are higher than that in harp system.
So for Large-span Bridges Fan system is appears to be less suitable.
5) Pylon Height to Span Ratio
Deflection of the deck significantly decrease as the pylon height to span ratio H/L increases.
6) Exposure Conditions
7) Foundation Condition

Aim : A critical Analysis of Bandra-worli Cable stayed bridge, Mumbai
Author : C.S.W.DAVIS
Abstract :The span of main cable stayed bridge 600m , consisting of two 250m cable supported
spans and two 50m conventional approach spans.
1)FOUNDATION
The drilled shaft method of construction was used to for the shafts.
The shafts vary considerably in size, depending on the bedrock “Rock encountered at the site
included highly weathered, fractured and oxidized volcanic material with RQD’s of less than
25 percent and unconfined compressive strengths of 1 MPa”.
Foundations for the towers comprised of 52 2m diameter piles arranged in a H shape to
capably support the legs of the pylon, they are up to 34m in length.
2)PYLONS
The main span bridge has 2 pylons, each with 4 legs, each tower is inclined towards the other by 10°, eventually merging at 98m above deck to become a single tower.
3)CABLE
In total there are 264 cables attached to the towers, they form a semi-fan arrangement.
Cable spacing is 6.0 meters along the bridge deck.
4) DECK
The deck of the Bandra Worli Sea Link consists of a hollow concrete box section with 3
cores, the dimensions of the deck varies throughout the length of the bridge.
The pre-cast segments vary in length from 1.5m to 3.1m. Each section of bridge deck will be
post tensioned following installation.

Aim : Behavior of a multiple spans cable-stayed bridge
Author : S. Arnaud, N. Matsunaga, S. Nagano & J.-P. Ragaru
Abstract : We got the opportunity to participate in the design check of a five towers cable-stayed
bridge with 300 meters spans and we examined the configuration between type of
connection, stiffness of deck, stiffness of piers and pylons, in order to confirm the
minimal structural cost.
One of the main problems of bridges with multiple cable-stayed spans is the behavior under
live loads,as the deflections and bending moments in the deck are more influenced by the
stiffness of the pylons and by the connection between deck and pylon than for a standard
cable-stayed bridge.
The second problem is the effect of deck length variation due to temperature and concrete
creep and shrinkage.
further calculations about the relationship between stiffness of deck, pylons and piers.
Results are presented with particular focus about the impacts of asymmetric loading and
thermal expansion of the deck on this multiple spans structure.
Fig 2 Connection of Deck & Pylon
Conclusion :The main conclusions of this study about behavior of multiple cable-stayed spans
bridges under live Loads and thermal variation are:
The connection type c (tower and deck sliding on pier) is the more effective and economic for
the studied load cases.
For the connection type c, it is efficient to reduce the deck rigidity and to increase the pylon
rigidity.
The connection type b (deck embedded in the pylon) can be more efficient, but we shall
solve the problem of the extension under long time variations.
The type a and d structures (deck simply supported on pylon or fully suspended) are less
efficient under live loads and thermal variation, with more forces on the foundations and
more force in the deck.

Aim : Analytical Investigation of Cable Stayed Bridge Using Various Parameters
Author : Parag R. Nadkarni, Padmakar J. Salunke, Trupti Narkhede
Abstract : In this paper, analysis of 240 m long fan type cable stayed bridge having single planeof cables is carried out with the help of software facilities.
Effects of various parameters such as stiffness of deck and pylon and number of cables on the
behavior of cable stayed bridge were observed.
Number of models of cable-stayed bridge generated in software SAP-2000.
From the analysis of number of models, The effect of parameters is studied through
comparison of bending moments at following critical locations.
1) Sagging moment at mid span of central panel of deck
2) Hogging moment in deck at pylon location
3) Moment in Pylon at deck level
Conclusion : various effects on maximum moments in deck at mid span of central panel and at
pylon location and maximum moment in pylon at deck level were observed in governing load
combinations which are as follows.

From all these observations, it is seen that stiffer sections of deck and pylon will produce
more bending moments in the corresponding bending moments.
It is preferable that slender sections should be used for deck and pylon so as to achieve
economical solution. Further, use of more number of cables reduces bending moments in
overall structure.
