Burj Al Arab: the Only 7-Star Hotel in the World
TRAVEL Burj Al Arab: The only 7-Star Hotel in the World by Engr. Chin Mee Poon, FIEM, P. Eng. ON our way back from Scotland, my wife and I stopped over at Dubai for three nights to see how much the place has progressed since our last visit in 2002. Dubai is a tiny emirate situated near the tip of a promontory of the Arabic Peninsula that separates the Persian Gulf from the Gulf of Oman. It is the second largest of the seven emirates that make up the United Arab Emirates, one of the richest Arabic countries. Before oil was discovered in the 1960s, Dubai was poor and its people lived a nomadic life in a desert environment. In less than half a century, the desert land on both sides of Another first is, of course, the well-known Burj Al Arab, the Dubai Creek has been transformed into a large oasis of often touted as the world’s only 7-star hotel. Built on an concrete jungle, and this oasis is still expanding with more artificial island in the vicinity of the luxurious 5-star Jumeirah giant structures shooting up to scrap the sky. Beach Hotel, this all-suite hotel is in the shape of a sail. It is estimated that 20% of the world’s tower cranes are At 321m, it is also the tallest hotel in the world. And with currently employed in Dubai. Of its population of about its cheapest suite going for about Dh3,500 (about RM3,500) a 1.5 million people, almost 80% are foreign workers from night, it is definitely the most expensive hotel in the world. -

Burj Khalifa Tower
Burj Khalifa Tower The tallest structure in the world, standing at 2,722 ft (830 meters), just over 1/2 mile high, Burj Khalifa (Khalifa Tower) opened in 2010 as a centerpiece building in a large-scale, mixed-use development called Downtown Dubai. The building originally referred to as Dubai Tower was renamed in honor of the president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan. Burj Khalifa Dubai, United Arab Emirates Architecture Style Modern Skyscraper | Neo-Futurism Glass, Steel, Aluminum & Reinforced Concrete Prominent Architecture Features Y-Shaped Floor Plan Maximizes Window Perimeter Areas for residential and hotel space Buttressed central core and wing design to support the height of the building 27 setbacks in a spiraling pattern Main Structure 430,000 cubic yards reinforced concrete and 61,000 tons rebar Foundation - 59,000 cubic yards concrete and 192 piles 164 ft (50 m) deep Highly compartmentalized, pressurized refuge floors for life safety Facade Aluminum and textured stainless steel spandrel panels with low-E glass Vertical polished stainless steel fins Observation Deck - 148th Floor PROJECT SUMMARY Project Description Burj Kahlifa, the tallest building in the world, has redefined the possibilities in the design, engineering, and construction of mega-tall buildings. Incorporating periodic setbacks at the ends of each wing, the tower tapers in an upward spiraling pattern that decreases is mass as the height of the tower increases. The building’s design included multiple wind tunnel tests and design adjustments to develop optimum performance relative to wind and natural forces. The building serves as a model for the concept of future, compact, livable, urban centers with direct connections to mass transit systems. -
Burj Khalifa Gatehouses
Burj Khalifa Gatehouses Dubai, United Arab Emirates Burj Khalifa Gatehouses Dubai, United Arab Emirates As the world’s tallest building and Dubai’s top tourist destination, Burj Khalifa has thousands of visitors daily, most of whom arrive in automobiles—each of which must undergo security inspection. SERVICES A key component of that mission is the AS+GG-designed gatehouses, which are as beautiful as they are functional. Architecture In keeping with the client’s desire for a consistent style for all structures within the Burj complex, the gatehouses take their aesthetic cues from the tower and related offi ce building. The curving lines of the gatehouses derive from the CLIENT Emaar Properties undulating form of the tower massing (opposite page, left) and site design; the stainless steel cladding is similar to that used in the tower’s mullions and spandrels, while the panelization echoes the modular framing of the curtain wall. There are six gatehouses in the Burj Khalifa complex, each with its own function and identity, including the main hotel entrance, the main residential entrance, the hotel entrance, a taxi stand, the offi ce annex entrance and the truck service entrance. Some of the gatehouses have electronic automobile scanners, the housing for which was designed by AS+GG. All of the gatehouses feature teak louvers and ceilings (for added functionality and contrast with the stainless steel exterior walls and columns) as well as offi ces with observation rooms for the security checkpoint staff. The offi ce windows are glazed with tinted glass that provide additional insulation and glare mitigation while shielding the staff from view. -

Excitations can be caused by wind forces, pedestrian traffic, machinery or earthquakes. Natural frequencies and damping are typically low for these structures. With GERB tuned mass dampers (TMD), these vibrations can be easily reduced. All GERB TMDs, both vertical or horizon- tal, have three main components: Spring or pendulum – Oscillating Mass – Viscodamper® (viscous fluid damper). Every TMD is exactly tuned to the main natural frequency of the structure.

Burj Khalifa, the Shard, and Rivals by Eva Bogomil
Burj Khalifa, The Shard, and Rivals by Eva Bogomil Introduction From the early days, we have invariably been interested in the world we live in, exploring, analysing, and altering it at our will. Humanity has gone a long way from caves to modern skyscrapers, aiming for ever greater heights. The power of human ingenuity has conquered the elements to reach the sky and beyond. Nowadays technologies allow us to build skyscrapers that totally change our idea of a modern world. Throughout the centuries brilliant engineers have been inventing more advanced and complex technologies, expanding our abilities. The Acropolis, St Paul’s Cathedral, the Eiffel Tower and the Sydney Opera House are all marvellous buildings that have remained objects of admiration for historians, architects, and artists, as well as a source of inspiration for many generations. Even to the general public the structures appear breathtaking. The 21st century saw the dawn of super-skyscraper construction. The Shard, Taipei 101, the Princess Tower, the Abraj Al-Bait Towers, and the Shanghai Tower are just some of the outstanding examples the modern world can be proud of. Burj Khalifa, currently the tallest building in the world, crowns this list of our achievements (Figure 1.0) which keep attracting people, making them wonder how such structures could have been built. Figure 1.0: Height comparison of some of the tallest buildings in the world This essay will focus mainly on London’s Shard and Dubai’s Burj Khalifa. Both of these skyscrapers are unique in their own way, yet similar. The Shard — currently the tallest building in the United Kingdom — dominates London skyline. -

One of the most important reasons driven the achievement is the continuously evolvement of structural systems. In this paper, previous classifications of structural systems are summarized and different types of structural systems are introduced. Besides the structural systems, innovations in other aspects of today's design of high-rise buildings including damping systems, construction techniques, elevator systems as well as sustainability are presented and discussed.
