5 Of The Worlds Biggest Metal Structures

Posted by Andreas Christodoulou

Description :

The largest buildings in the world are not necessarily the tallest. Many of those with the largest square footage exploit the benefits of steel construction. Structural steel, according to the American Institute for Steel Construction, is not only the most cost-effective framing system, but the quickest to erect and one of the most easily recycled. Five of the world's largest buildings are prime examples of the possibilities of steel. 

Venetian Macao 

The world's sixth largest building is its most extensive casino, the 10.5 million square foot Venetian Macao built on reclaimed land in Macao. Designed as a "mega-resort," the facility is operated by the Sands, the famous Las Vegas resort. 

It's ornate murals and cornices, its arena, its pool and spa complex and even its network of canals with their gondoliers beneath a painted sky are all attached to a structural steel frame.

Dubai Terminal 3 

The second largest building on earth is now one of the international terminals of Dubai International Airport. Terminal 3's 18,440,000 square feet of floor space originally served only domestic travelers, but now handles international flights as well. 

Over 40 million passengers use the terminal every year. Completed in 2008, the building required 33,000 metric tons of structural steel. As if it were not big enough on its own, Terminal 3 is directly connected to Terminal 2 through a common transit area. 

Bloemenveiling Aalsmeer 

FloraHolland's auction facility in Aalsmeer in the Netherlands is the largest trading floor in the world at 10.6 million square feet and the fourth largest building overall. 

Originally erected in 1972, the building was expanded to its current size in 1979. Its steel roof members are plainly visible from the auction floor. 

Chrysler Headquarters 

The headquarters and main R&D facility for Chrysler LLC is a 5.3 million square foot tower in Auburn Hills, Michigan, a suburb of Detroit. 

The building's curtain walls hang from a steel frame, incorporating atriums and concourses that culminate in an octagonal skylight. The facade is designed to allude to the shape of an automobile, something not possible without steel frame construction. 

Abraj al Bait 

The most extensive building in the world is Abraj al Bait in Mecca, Saudi Arabia. It includes a luxury hotel, a four level shopping mall, six residential towers for permanent residents, a conference center and two separate heliports and an intramodal transit station, as well as the world's largest clock tower.

While its exterior incorporates Islamic architectural motifs, particularly mosaics, the building's internal structure is a steel frame. 

Almost all the world's largest building's use structural steel framing. The one exception, the 6.6 million square foot reinforced-concrete Pentagon, was built during a time of steel scarcity. The contrast between its low, glowering facade and light, airy curtain wall structures is in itself an argument in favor of steel frame construction. The American Iron and Steel Institute maintains that steel offers economic and environmental advantages in addition to its "aesthetically beautiful" appearance. This makes it the medium of choice for contemporary architectural expression.

The Advantages of using Steel as a Construction Material

Posted by Andreas Christodoulou

Description : 

Steel may not be an immediate answer when being asked about the best construction materials, but it certainly should be up there. Other than its strength there are so many advantages of steel that most wouldn't know of, take a look.

The main problem faced by any construction company is whether the materials are strong enough and durable enough to build the structure that they desire. When buildings are built using a metal frame using materials such as steel, this is not an issue, due to its strength and the strain it can be put under.

There are so many advantages of using steel as a construction material; to start with, it's extremely popular for its sturdy and unwavering properties. Steel has an immense resistance barrier and is completely protected against rust, corrosion, variations of weather and climate and other environmental dangers such as pollution; this makes steel the metal that's most suited to an exterior surface of a building.

Building using a steel structure also gives the building internal strength, meaning it will remain stable and standing for longer. Another reason that steel is such a good material for building is that it is immune to infestations of termites and other pests, so the internal structure of the building is always solid.

Building using steel is said to be the cheapest and most effective way of making a fire proof home. Steel is resistant to a number of forces including most extreme weather such as fire and wind and also against chemicals, whether they are toxic or not, they are extremely unlikely to get through steel. Steel is also great for the environment as almost all steel that is in circulation today is recycled and if it's not recycled it will be eventualy. As steel is recycled it doesn't lose any of its great properties, it's still just as strong and durable, it remains just as resistant to extremes as when it is brand new.

Steel can take an awful lot of strain; in fact it has the highest strength to weight ratio than anything else that's used in the construction industry. Steel is a relatively light metal used for building and is therefore used a lot for pre-engineered buildings. Steel is also great for buildings as it gives immaculately straight walls and square corners. 

All of these points show quite a few of the benefits of using steel in construction and overall that steel makes the safest buildings, it obeys all building rules and regulations whilst also being the strongest metal for building and having the capabilities to protect its inhabitants from all sorts of weather extremes, such as hail storms, strong winds and even - in some parts of the world - hurricanes and tornados.

World's Smallest V12 Engine - Built From Scratch - Power To The Handy People!

Posted by Andreas Christodoulou

Description :

Wednesday, back at work, back into the swing of things. Morning all! If you're new here, you may want to subscribe to our RSS feeds. Thanks for visiting!

German engineering outshines every other automobile making nation simply because they are so good at it. But an enthusiastic German automotive part maker, Ralf Drendel, obsessed with V12 engines has upped the ante on the miniature scale, so to speak.

 Made perfectly to emulate the real thing (V12 engine) the miniature V12 is designed to function perfectly with any high-end RC (Remote Controlled) vehicle; be it a RC plane, boat or car.

Having 12 cylinders housed inside a four stroke engine runs on a mixture of high performance synthetic lubricant (10%), Methanol and Nitro methane (5-10%) and produces power of 6 to 8 horsepower with a displacement of 87-cubic centimeters.

This functional model has twin camshaft and overhead valves and doesn’t require any radiator, to add to that the crankshaft has been made from multiple pieces.

Frame of the engine has been made from stainless steel, bronze and aluminum and the finished engine runs on compressed air to cool down and ward off any heat produced.

According to Ralf, the maker of this engine, kits will be available anytime soon so that you can attach this German beast to your choice of miniature vehicle with minimum hassle. So hose, just sit back, hit the play button on the video given below and enjoy the thumping sound of the mini V12 in action.

For those who are interested in watching the whole making of miniature V12 engine watch the video given below, you’ll surely be awe-inspired by it if you are an automotive junkie. :)

New "Passing Cloud" Airbus Design

Posted by Andreas Christodoulou

Description :

This project was designed by Tiago Barros and envisions a distinct approach towards moving around the United States being also a revival of the act of traveling. 

Why traveling at high speed? Why having the final destiny always defined? And why always departing and arriving on a tight schedule? Nowadays, everything is set and everyone is always running around. It is time to reconsider the act of traveling and start enjoying it accordingly. 

The Passing Cloud is an innovative and environmentally friendly method of transportation that doesn’t require expensive steel tracks or concrete highways. It is made of a series of spherical balloons that form the shape of a cloud. 

Its inner stainless steel structure is covered with heavy weight tensile nylon fabric. During the journey, It moves according to prevailing winds speed and direction at the time of travel. Since it moves with the wind, no wind is ever felt during the trip, offering the passengers a full “floating sensation”. 

It’s an unique journey. The feeling of floating in the atmosphere - on top of a cloud - with an open schedule and unknown final destiny. All National Ground would be potentially covered at virtually no cost and the help of the wind. The journey becomes your destiny.

Passing Cloud is a recently submitted project for the international ideas competition : Life at the Speed of Rail, organised by the Van Alen Institute and partly funded by the Department of Cultural Affairs of New York City. 

Although it wasn’t one of the winning proposals, Passing Cloud reveals a strong conceptual approach that is worth noting : It is a new vision on traveling, based on the old Zeppelins.

Nowadays, traveling is achieved with this idea of having a fixed destination and an estimated time of arrival. Passing Cloud completely inverts this system. A floating device is introduced that travels around the entire USA territory according to current predominant winds. It has no fixed time of arrival or place for arrival. The journey becomes the essence. Imagine traveling at wind speeds in a totally sustainable object that leaves no Human trace behind.
