India is on the path
of becoming a developed nation by 2020 on the back of a
resurgent and demand driven economy. Steel plays an important
role in development of any country; the same is the case
in India - when India's GDP is growing at the rate of 8%
for last three years. Steel consumption is growing at the
rate of 10%. Both the targeted 12% growth of manufacturing
sector and infrastructure growth will demand a large quantity
of steel. Steel sector has to play a key role in the growth
of infrastructure and manufacturing sector.
India has a long way to go both on the growth of manufacturing
sector and infrastructure. Dam, power generation and distribution,
bridges, parking places, railways, ports, airports have
to expand and modernize. In the present scenario, Steel
Industry has to take center stage, as it's another industry
for growth of all industries and infrastructure. Phenomenal
growth of steel industry is mandatory for the overall growth
of economy. Steel production capacity has to double or triple
to meet the growing demand. Thus steel industry requires
adequate govt and people attentions. With liberalization
of Indian economy public & several private players of
steel the capacity has doubled in the last decade with an
average gr owth rate of 9.3%.
With capital investment of over Rs.1,25,000 crores, the
Indian steel industry currently provides direct / indirect
employment to over 2 million people. Steel industry has
to play an important role in transforming India into an
economic super power global experts visualize as the future
second largest steel producer in the world. The Indian steel
industry is willing to play its role in achieving its target.
India's domestic steel consumption of 41-42 million ton
amounts to per capita consumption of 38 kg only against
world average of 170 kg and Chinese average of 250 kg. There
is huge untapped potential for consumption in India as steel
is yet to touch the lives of millions of people.
For realization of goals and achieving desired growth of
Indian steel industry some constraints like inadequate infrastructure,
high cost of basic inputs like power,natural gas and railway
tariff, lack of coking coal reserve, high cost of capital
and high tariff / non tariff barrier imposed on Indian exports
have to be addressed seriously. The only two major competitive
advantage of Indian steel industry are assured access to
Indian iron ore supplies and cheap labour, which is partly
balanced due to poor labour productivity.
In view of the above, the constraint mentioned must be
removed quickly and competitive advantages must be maintained
in the area of trained manpower and iron ore availability.
Two obvious conclusions based on the above are :
-
To generate large number of trained
manpower base to run 100 MT steel industry.
-
Control on iron ore export to make
it available for the growing steel industry. It is much
better to export steel than iron ore as is being done
by all wiser nations.

VIVOCITY,
SINGAPORE
A large quantity
of circular hollow sections has played an integral role
in creating a surfing theme for the city's harbour front
development known as VivoCity. Designed by Japanese
architect Toyo Ito, the wave inspired façade
and roof needed 280t of steel. This enabled the contractor
to eliminate double handling by arranging direct delivery
to the fabrication yards in full 40t container loads.
The development holds more than 300 retail outlets,
an amphitheatre, a 7000 m open air plaza and a 300m
harbour front boardwalk. VivoCity is set to become Singapore's
largest and most diverse retail and lifestyle destination.

CITY COUNCIL
Leicester City
Council is one of the most innovatively designed theatres
ever built in UK. It was intended to be as open as possible
to the public gaze which meant the inner workings of
the theatre, its craft and technical components, was
to be exposed to the street and allow passers-by to
view such things as rehearsals, scenery construction
and costume making. One side of the theatre abuts a
multi-storey car park and consequently didn't need to
be glazed, but the other three facades lent themselves
to the impressive sweeping glass frontage of the complex.
In order to maintain the transparent vision for the
structure it was decided to have as few view-blocking
columns along the façade as possible. To achieve
this, there are in fact no structural columns and everything
is suspended from the roof. This includes the façade
and walkway, a 125m2 conference room and all heavy plant.
The Steelwork
contractor has erected more than 3,000t of steel for
the roof structure, with the remainder of its final
5,200 tonnage being accounted for by two steel-framed
shoulder blocks which will house administration offices,
workshops and changing rooms. The steel roof is made
up of a number of 6m deep trusses which have varying
spans from 25m to 30m. The glazed façade, walkway
and its concrete deck, are also suspended from the huge
steel roof via 18m-long tapered columns, spaced at 6m
intervals. As most of the truss sections did not exceed
30t in weight, one 500t mobile crane and two tower cranes
lifted all the roof steel members into place. The Leicester
Regeneration Company foresees the Performing Arts Centre
and the surrounding Cultural Quarter as key to the city's
renaissance.

WHITE CITY STADIUM,
WESTFIELD LONDON
The 150,000m
White city Stadium in Shepherd's Bush, Westfield London
include more than 300 shops, five anchor department
stores, numerous restaurants and bars, a 14-screen luxury
cinema; health and beauty retreat, gymnasium, vast interior
space known as the Pavilion - and parking for 4,500
cars. The central section of the car park areas have
been constructed using concrete encased steel, with
everything above the car park now essentially steel
framed with a total consumption of 25,000t of Steel.
With the majority of steelwork being erected in eight
metre grids, this has meant a rapid installation of
upper levels. Some areas within the project which were
originally to be built using concrete are now steel,
such as the lower retail level. The project required
trusses up to 17t in weight. Three large steel trusses
and a number of smaller trusses will be erected at roof
level to link the cinemas. The three biggest, weighing
27t, and measuring over 24m long was brought to site
in sections and assembled and lifted as complete sections
by one of the on-site high capacity tower cranes. The
structural modifications have involved a number of steel
columns being re-moved to give a larger 16m x 8m grid
plan. The final design is a 150m x 50m lattice frame
multi-curved roof supported by these seven steel tree
columns. Assembling the roof structure will be a colossal
procedure, and will involve the sub-contractor supplying
460t steelwork. Each truss consists of a number of six-pronged
nodes connecting to 200mm x 100mm RHS's, thus forming
a grid for either triangular glass panels or cladding.
Westfield London also forms part of a massive regeneration
project in west London.

ATRIA MILLENIUM MALL,
MUMBAI
The Atria Millennium
Mall Architected by Hafeez Contractor and Engineering
by Construction Catalyser has the right ingredients
to assist the creation of a striking piece of architecture.
The most attractive is the huge and dramatic wave roof,
spanning an area of about 13000 sq. feet. Using high
strength grid steel work, it is especially designed
for minimal thickness. The razor thin edge of the roof
is visible along its front giving it a flowing, fabric
like appearance. The roof grid is covered with insulated
metal cladding made of galvanised polycoated profiled
sheets with sound barrier below along with vapour, sound
and thermal insulation above. One of the main supports
of the wave roof are two tree-like columns. Emerging
as a single slender trunk from the ground, they branch
into four different struts, which touch eight locations
on the roof. Another structural element, which essentially
supports the roof and yet is a marvellous facet for
the mall is a glass curtain wall. This is a saddle shaped
and bi-directionally curved pre- stressed two-way cable
net. The overall size is about 25mX25m while each individual
laminated glass panel is of 1.5mX1.5m. These glass panels
are fixed to the cable with specially designed bearings
and point support fixtures like spiders. The edge beam
at the extreme of this cable net wall is a circular
pipe bent into the complex profile. Along with the tree
columns, steel struts, which take up the doubly glazed
units of the restaurant at the upper level, also support
the wave roof. The Atria Millennium Mall is a structure
that expresses bold modern thought with confidence and
innovation. It uses state of the art technology and
materials to create a contemporary design with an everlasting
impact.

LEO BURNETT, MUMBAI
The
structural solution for the Leo Burnett office building
in Mumbai by Construction Catalyser demanded the use
of Steel as a major framing material. Mezzanine and
ground floor are connected visually by staircase cut
out and share a skylight. The mezzanine has a huge space
with few columns measuring 40 m x 40 m to facilitate
flexible planning for design studio. The structural
system consists of framed steel beams and columns with
the maximum depth of beam controlled 450 mm spanning
9 m. The mezzanine slab is a composite slab of corrugated
metal sheet with reinforced concrete on top. Corrugated
metal sheet has been used as lost shuttering which gives
finished ceiling thus eliminating the requirement for
false ceiling. For the roof cable stiffened beams with
box sections were used which are optimized in material
and strength. Box section takes the compression on top
and cables for tension in the lower section of the beam.
Since there is no false ceiling services are exposed.
The beams have helped in flexible planning of service
lines.

| DESIGN OF HAUNCHED
COMPOSITE BEAMS IN BUILDINGS |
This
Publication presents a method of design for haunched composite
beams as used in buildings. Moment continuity is developed
between beams and columns by 'haunches', i.e. local deepening
of the beam section. The publication describes two approaches
to determining the global moments in the structures; by
elastic design or by plastic hinge analysis. The moment
resistance of the composite section is based on plastic
section analysis in both cases. Checks are made on the
lateral stability of the beam both in the construction
and in services conditions. Serviceability calculations
are made for deflection, stresses and vibration response.
The publication also includes a detailed procedure for
design, including that of the connections. Initial sizing
of the members is also included in the Scheme Design.
A fully worked design example is presented.

CONNECTIONS TO STEEL FRAMES |

The
correct design of connections between cladding panels
and steel frames is of critical importance to the performance
of the cladding and to the building programme. Since cladding
is a critical path operation, cladding connections have
to be developed such that they not only have sound structural
and physical properties, but also permit efficient and
rapid erection. A characteristic of many of the most successful
cladding systems is that much preparatory work (lining
and leveling etc) id done in advance of the erection operation,
and therefore off the critical path. Section 1 of this
publication details the advantages of such practice and
Section 2 appraises six generic cladding systems in relation
to the optmimised practices set out in Section1.INS/PUB/087

| DESIGN OF STEEL-
CONCRETE COMPOSITE BOX GIRDER FOR RAILWAYS (24.4 M&
30.5M SPANS) |
The
publication is aimed at introducing and popularising the
use of Steel-Concrete Composite Box Girder Bridges in
Railways as a cost effective alternative to the present
practice of using PSC girder for higher spans such as
24.4 m and 30.5 m. Since steel box girders have been well
known for their cost effectiveness, it is essential that
a few steel box-girder designs with concrete slab at top
are developed using foreign and Indian code stipulation
for adoption by Railways so that economical solutions
can be arrived at for spans where plate girders become
uneconomical. This publication will be very useful to
railways in the present scenario where lot of PSC bridges
are getting distressed before reaching their desired design
life. INS/PUB/094 - Price: Rs.400/-
