2. Wuhan Greenland Center – Rising from its site on the Yangtze River waterfront, the Wuhan Greenland Center symbolizes the growing vitality of Wuhan, the most populous city in central China and a major player in the country’s economy due to its status as a multi-modal transportation hub.
Like many towers that seek to transcend the 600-meter threshold, wind and seismic considerations were paramount in the design process. To address these issues, the tower uses a triangular floor plan that gently narrows along its height to provide extra stability that protects against intense winds and seismic events. Three large sloping steel-reinforced concrete (SRC) columns rise and join at the top of the building to form the 61-meter crown structure that rests above a glass dome. By omitting portions of floors and perimeter framing at different elevations, “slots” are created in the building envelope to provide a distinctive architectural personality while reducing wind loads on the structure. In this respect, the locations and geometry of structural components have been carefully optimized to not only provide strength and stiffness but integrate seamlessly with the form of the building.

5. Global Financial Center Tower 1 – The design of Global Financial Center Tower 1 represents an exercise in both simplicity and iconicity. At the ground level, the tower meets the street at the human scale, with conical extrusions that downplay its verticality near the entrance. These canopies recall the nomadic tent entrances of the Qing Dynasty. Rising upward, the tower widens slightly before it tapers, giving it an oblong appearance. For structural consideration in a high seismic zone, the tower shaft evolves from a square to a convex plan with corners carved out to further reduce the considerable bulk of the tower and to soften the scale contrast with the surrounding residential towers. At the top, an executive club is located within a giant “pearl” that measures 50 meters in diameter. The pearl – a symbol of wisdom, luxury, and purity – is the jewel in the crown of this mixed-use development.

Engineer Toby McCartney wants to use recycled plastic instead of oil to repair some of the world’s 40 million kilometers (24.8 million miles) of road. The idea would solve more than one problem: poor road quality, the continued use of fossil fuels, and the waste plastic epidemic. His Scottish start-up, MacRebur, mixes waste plastic into asphalt to create roads that last longer and are less prone to getting potholes.
Some of the waste plastics retrieved by the pickers were put into potholes, petrol poured all over them, and the rubbish set alight until the plastics melted into the craters to form a makeshift plastic pothole filler.
Upon returning to the U.K., Toby got together with his two mates, waste expert Nick and construction engineer Gordon, and formed MacRebur. They take waste plastic that is destined for landfill sites and recycle it. They use a special formula to clean it off, create pellets using it, and then use those pellets to add to a mixture of rocks and bitumen to make longer-lasting roads.
So far, the scheme has won the approval of Virgin founder Sir Richard Branson, and McCartney’s company MacRebur has gotten the support of two local governments in England to start using MR6, MacRebur’s patent pending, high performance, asphalt binder additive to build their roads.
We reckon we could use some plastic roads in Australia too!
Thanks to Hyperloop Technology, travelling from Melbourne to Sydney could be hopefully done in under one hour!
But what is Hyperloop? And how is it going to change our travelling lives for the better?
Hyperloop has significant advantages for travelers, the economy, and the environment. Eventually, it will be able to travel far faster than any method of land based transport currently available — with its closest competitor, the bullet train, only capable of speeds of 320 km/h (200 mph). Projections indicate that it will also be cheaper to build than bullet train systems.
VicHyper wants to revolutionise the future of transport in Australia. Their CEO, Zac McLelland who is based at RMIT, said the hyperloop technology which had the potential to leapfrog fast rail and link the cities with ease, existed. It was now just a matter of putting it into practice. “If we really wanted to do it, we could do it now, and be built within three to five years,’’ Mr McLelland said.

This is a fascinating documentary on eight of the most ambitious mega-projects currently under development around the world, featuring: Istanbul’s building boom (Turkey); the Mission to put a human on Mars; the effort to develop Lagos (Nigeria); Africa’s unprecedented clean energy opportunity; the project to probe the nearest Earth-like exoplanet; Atlanta’s stadium of the future (Georgia, United States); India’s effort to modernize its highways; and China’s unprecedented One Belt One Road, “New Silk Road” initiative.
It’s a massive project with many roads, railways, ports and maritime routes making up new and revived trade corridors. The land-based projects are the belt. The road is the maritime routes that will connect up China’s southern provinces to south-east Asia and the east coast of Africa with ports and railways.
For those who are uninitiated, the “Silk Road” was an ancient network of trade routes that were for centuries central to cultural interaction originally through regions of Eurasia connecting the East and West. The Silk Road concept refers to both the terrestrial and the maritime routes connecting Asia and Europe.
While the term is of modern coinage, the Silk Road derives its name from the lucrative trade in silk (and horses) carried out along its length, beginning during the Han Dynasty.
We just love bridges. They come in all shapes and sizes and play a major role in uniting our communities and enhancing our everyday life. Here we highlight five of the most famous bridges in our world today starting with our very own Coathanger.
Sydney Harbour Bridge
The Sydney Harbour Bridge links Sydney’s two major commercial centres and forms a daily orientation point for millions. It is a living landmark, a tourist experience and an essential transport line for Sydneysiders. It is a cultural landscape that people actively experience: driving, walking, sailing, flying, cycling, ferry and train commuting, as well as passively observe – from the foreshores, from a distance, as a distinctive landmark – or examine in detail as a marvel of engineering technology.
Golden Gate
The Golden Gate bridge is still considered one of the world’s engineering masterpieces. Today it carries over 100,000 vehicles per day (northbound and southbound). The Golden Gate has endured as a marvel of modern engineering; its 4,200-foot main span was the longest for a suspension bridge until 1981, while its 746-foot towers made it the tallest bridge of any type until 1993. It withstood the destructive Loma Pieta earthquake of 1989, and was closed to traffic only three times in its first 75 years due to weather conditions. Believed to be the most photographed bridge in the world, this landmark was named one of the seven civil engineering wonders of the United States by the American Society of Civil Engineers in 1994.
Qingdao Haiwan Bridge
In 2011, the Qingdao Haiwan Bridge became the world’s longest sea bridge. At 42.6 km long, it is nearly 5 kilometers longer than the previous record-holder, the Lake Pontchartrain Causeway, in Louisiana, USA. Costing $8.6 billion, the bridge links Qingdao city in China’s eastern Shandong province with the Huangdao district. The former is considered as the national tourism city of China and Huangdao is a suburban region which is moving towards becoming the next booming economic region. And the bridge is, therefore, is a great asset for tourism and trade.
Øresund Bridge
The Øresund Bridge is an approximately 16-kilometer long road and rail link between Sweden and Denmark. It connects Copenhagen to Malmö fostering economic growth and cooperation for both cities. The link consists of three sections, a bridge, an artificial island and a tunnel, and the bridge accounts for half the length, with a railway and motorway running on separate levels. The bridge has provided a foundation for stronger and more extensive cooperation regarding economy, education, research and culture between Sweden and Denmark.
Millau Viaduct
Millau Viaduct is ranked as one of the great engineering achievements of all time. It opened in 2004 and was built across the Tarn valley to alleviate holiday traffic between France and Spain. This bridge broke several records. It has the highest pylons in the world (245 meters and 221 meters), the highest bridge tower in the world (343 meters) and the highest road bridge deck in Europe (270 meters). Millau Viaduct is so high that it glides above the clouds. In 2006, Millau Viaduct received the Outstanding Structure Award by the International Association for Bridge and Structural Engineering.
In this video we will learn about vortex shedding and mass dampers.
Vortex shedding happens when wind hits a structure, causing alternating vorticies to form at a certain frequency. This in turn causes the system to excite and produce a vibrational load. Historically, it has been very difficult to calculate by hand. Today, with modern technology and new engineering practices, completing a vortex shedding analysis is a valuable tool used in the design of tall equipment and structures.
What is Mass Damper?
Mass Damper is the system that’s used to control movement in skyscrapers by reducing both the speed at which the building oscillates and the distance those oscillations cover. Mass dampers consist of large pendulums—usually steel plates bolted together to form a solid chunk—suspended from cables near the top of the building. When the building sways in a gust, the weight’s inertia acts as a counterweight, pulling it in the opposite direction.
