| Steel
is Environment Friendly: |
| Steel
is completely recyclable. Half of all the annual world steel
production comes from recycled material. Old steel is raw
material, not waste! Unlike other materials, steel must not
be burned or disposed off at waste disposal sites. Thus, steel
makes a major contribution to the protection of our environment.
Steel is a very environment friendly material. It also possesses
greater durability compared to other materials and requires
relatively low amounts of energy in its production. (Ref:
www.made-of- steel.com) |
| Steel
is everywhere in our life: |
| It
is wiser to ask where steel is not used than trying to figure
out where it is. Its presence can be felt practically everywhere
starting from a design of lighter to skyscrapers. Transportation
would be just as impossible without steel and also the same
for medical technology. (Ref: www.made-of- steel.com) |
| Steel
with Extraordinary Qualities: |
| An
extraordinary type of steel has been invented that looks more
like glass than metal. It is extremely strong, and developers
hope it could be used for tougher medical implants or lighter
aircraft. Amorphous metal alloys are generally very expensive.
Those on the market are composed mostly of costly zirconium
or palladium. Glassy steel could reduce the price tag of amorphous
metals from $ 220/kg to less than $ 33/kg.(Ref : Steel Scenario

| Steel
gets a Human Touch: |
| Indian Steel
Alliance (ISA), an association of major flat steel producers
in the country, has unveiled its advertising campaign in Mumbai,
intending to strengthen the Indian steel industry and highlight
the importance of steel in day-to-day life. The campaign’s
theme is ‘Magic of Steel’ and it brings to light
numerous applications of steel in lives of people, which normally
go unnoticed. (Ref: Steel & Metallurgy, May 2004) |
| Branding
Wire Rods: |
| Bhilai Steel
Plant has started branding its TMT wire rods. TMT wire rods
are designed to resist atmospheric and marine corrosion. The
product is used extensively as reinforcement material in the
construction industry as well as in the heavy industries as
wire ropes. TMT bars in various chemical compositions are rolled
to different diameters ranging from 5.5 to 12 mm plain and 8,
10 & 12 mm. The controlled cooled wire rods have uniform
mechanical and metallurgical properties, improved tolerance,
better surface finish throughout the length of the coil and
reduced secondary scale losses.(Ref : SAIL News Vol. 7 No. 3
June 2004) |
| Corrosion
controlled pipelines: |
| The enormous
cost of replacing corroded pipelines and other steel structures
is a constant problem for engineers and designers. This ever-increasing
cost is of great concern to constructors and owners all the
time. The most favoured form of pipeline protection is hot applied
plasticised coal tar or asphalt together with glass fibre reinforcement
as outer wrap. This conventional coat and wrap system provides
long term protection and is widely accepted as the most efficient
corrosion prevention medium. Pipeline owners prefer three-layer
Polyurethane coatings, which is one of the best available methods
today. However, the cost of three layer Polyurethane coatings
is extremely high. The other preferred method of coatings for
underground pipelines is by the use of anti-corrosive tape.
These tapes are very efficient in giving protection against
corrosion and can be easily wrapped around the pipe surface.(

automated car park: |
| The Chennai
Metropolitan Development Authority (CMDA) is planning an automated
car parking system either on a standalone basis or with a commercial
slot near Panagal Park at T. Nagar. The site is spread over
2,358sq. mt area. The parking slot is being developed as a pilot
project and its successful completion and operation may lead
to similar projects elsewhere in the city. The project will
be developed on BOT basis. CMDA is in the process of selecting
builders and developers for the project. (Ref: Project Monitor,

doors: |
| The modern
era has witnessed a sea change in innovative use of materials,
which can be attributed to changing lifestyle and aesthetics.
There is an increased requirement on safety and security. Many
residential and commercial buildings are opting for doors, which
provide safety, security and strength apart from aesthetics.
M/s Mexin International Ltd., USA specializes in manufacturing
steel security doors, fire proof doors, burglarproof doors with
a wood finish and aesthetic design is available in India as
Mexin Doors .(Ref : The Masterbuilder Apr- May 2004 ) |
| Custom
Duty Slashes: |
| In a recent
notification the Government announced the reduction of Customs
Duty on non-alloy steel, melting scrap for iron and steel and
ships for breaking. The revised custom duties include Non-alloyed
steel from 10% to 5%, Ship for breaking from 15% to 5% and scrap
used for making iron and steel has been abolished. Similarly,
the Counter Veiling Duty (CVD) exemption has now been withdrawn
on such ships and additional Customs (CVD) will now be payable
on import of such ships. (Ref: JPC Bulletin July 04) |

| Cable-
Stayed Pedestrian Bridge: |
| A new cable
stayed Pedestrain Bridge was been proposed over the river Lea,
a tributary of the Thames, in southeast Britain. The unusual
pedestrian bridge is planned to cross the river Lea, a tributary
of the Thames, in southeast Britain. The proposed Leamouth Bridge
is Y shaped in plan, splitting at the north end to form two
pedestrian access ramps, one descending to ground level, the
other linking to an adjacent viaduct. The 50 m long cable-stayed
span simultaneously tilts and rotates out of the way of marine
traffic.The structure is Y shaped in plan, splitting at the
north end to form two access ramps, one descending to ground
level, the other linking to an adjacent viaduct. At the nexus
of the Y, located at the water’s edge, is an abutment
topped by a 25 m high mast. What makes the concept unique is
that it is a combination of a cable-stayed bridge and a movable
bridge. Moreover, the spindle, or axis of rotation, is not horizontal;
rather, it is at an angle, causing the span to rotate to the
side as it rises in a graceful arc until the mast comes to rest
alongside one of the bridge’s two access ramps. |
| The ability of the mast to rotate backward toward the
access ramp will facilitate its construction. First the
bridge deck will be erected in the horizontal position.
Then it will be lifted into the air so that the mast,
too, can be constructed in the same state. Once the cables
have been installed, the bridge will be ready to rotate
back into its normal, closed position. Both the mast and
the main deck element will assume the form of a steel
box section. A grid of lightweight steel members covered
by an aluminum deck will cantilever from the main member.
The span will be approximately 50 m long and have a minimum
width of 4 m.(Ref :IEI News June 2004) |

| Sage
Gateshead Building: |
|
The curvilinear building with a dramatic
shaped roof standing nearly 38m high and curved steel
frame is nearing completion on the banks of the Tyne at
Gateshead Quays, UK. The Sage Gateshead building will
provide an international centre for music of all kinds.
Two beam sizes were used for the primary supports, one
838 x 292mm, weighing 226kg/m, while the other measured
762 x 267mm and weighed 197kg/m. Beams, made from S355\2G3
grade steel, 18.5m in length were bent using both hot
and cold bending technology. Over 100T of bent beam sections
were supplied. The glass and steel Sage Gateshead building
is due for completion in winter 2004/05. (Ref : The Structural
Engineer- 17 August 2004) |

| The
Rion-Antirion Bridge: |
| The Rion-Antirion
Bridge, one of the world’s longest cable stayed bridges,
spans the Gulf of Corinth and provides a permanent link between
the Peloponnese and mainland Greece. The bridge consists of
a 2,252 meter long 4 pylon cable-stayed bridge with a span distribution
equal to 286 meters, 560 meters, 560 meters, 560 meters and
286 meters. The upper soil layers are reinforced with inclusions,
which are 2 meter diameter hollow steel pipes 25 to 30 meters
long driven at a regular spacing of 7 meters. About 200 pipes
are driven in at each pier location. A three meter thick properly
leveled gravel layer tops them. The stay cables are in inclined
arrangements, with their lower anchorage on deck sides and their
upper is anchorage in the 35-meter high pylon head. They are
made of parallel-galvanized strands. The thickest cable is formed
of seventy 15mm strands. The deck is 27.2 meters wide with two
traffic lanes plus safety lane and a pedestrian walkway in each
direction. |
It is a composite structure with a steel
frame made of two longitudinal 2.2-meter high plate
girders on each side and transverse plate girders spaced
every 4 meters.
The top slab is made of precast concrete panels. The
deck is continuous and fully suspended for its total
length. Four damping devices connect the deck to the
top of each pier and limit the pendulum movement of
the deck during an earthquake. The dynamic relative
movement during the design seismic event is in the order
of ± 1.30 meter while velocities may exceed 1
meter per second.(Ref : 17 August 2004 - The Structural
Engineer) |

Transit System: |
|
The ‘Aerobus’ arial transportation system
has been planned for Weihai city of China. It consists
of concrete pylons and suspension cables which are supporting
a slender steel guideway. The system will link the Weihai
city with Liugong Island. At first glance, the harbour
crossing planned for Weihai, China, might appear to
be a suspension bridge. The structure will boast the
same gracefully curving suspension cables and tall towers.
The cables will support not a roadbed, however, but
a mass transit system consisting of vehicles suspended
from a slender steel track. Gerhard Mueller, who financed
the construction of a working demonstration system subsequently
dismantled, in Mannheim, Germany, developed the Aerobus
concept in 1970. (Ref: Civil Engineering, June 2004,
Volume 74, Number 6.)

| Mobile
Presentation Platform: |
| A mobile Presentation
Platform was conceived by four engineers. Developed by Jens
Schulz, Rasmus Giesel, Silke Nachtigahl, Alexander Hanowski,
the profmobil allows scientists and important speakers to literally
take their ideas to the common man. A few minor adjustments
unfold the unassuming rickshaw into a platform for the speaker
- complete with a comfortable rest and laptop link. The
vehicle relies on ultra modern communications and provides for
an integrated LCD display monitor to aid the speaker. The radio
mike relays the speech to battery operated loudspeakers which
broadcast it to the audience ensuring sustained audibility.
