The comparison of buildings in terms of structural and architectural designs will reveal variations on a variety of issues. In this case, the essay would equate to the Burj Khalifa and Eiffel Tower towers, all of which have been built uniquely and are considered to have drawn a large number of visitors from the West and other parts of the world. A structural comparison will be performed, including the cost and square meters covered by each.
Structure- can be described as something designed or built from separate interconnected parts that have a fixed position on the land. On the other hand, structural element - is a term used during the analysis to split a complex structure into simple components. These factors cannot be broken down, or somewhat they cannot be decomposed into any different kinds since they can be defined to be linear, volumes or services.
Burj Khalifa Tower
Burj Khalifa happens to be an enormous tower in the world, and it features the highest tower balcony show that is open to the public, it also has the highest mosque and the most elevated swimming pool as well. The tower was built by twelve thousand workers and engineers since its inception in the way back 2004. The cost of the building can be estimated to be about $1.5 billion, and it has an estimated area of 526.760 square meters, which in this case is divided into 171870 square meters of the residential units, and 27870 square meters are offices (Baker, 2015). The building is known to have redefined the design and engineering of the supertall buildings in the world. In its construction, it combined a cutting-edge technology and the cultural influences. It also serves as the global icon which is both a future model for the urban centers as it speaks to the worldwide movement towards the compact and livable urban areas. On the structural description of the tower, Burj Khalifa has a mixed-use program that focuses on the area’s development density as it provides direct connections to the mass transit systems. Khalifa’s architecture has embodied the references of Islamic architecture, but yet its reflection is in the modern global community which it is designed to serve.
Khalifa building is a Y- shaped plan which is meant to provide the maximum amount of perimeter windows in the living spaces without necessarily developing the internal usable area. As the tower rises, some setbacks occur at the end of each wing in an upward spiral pattern through which decreases the mass of the tower due to the height increment. The delays were modeled in the wind tunnel to provide to minimize wind forces in the building.
In this case, the Khalifa’s tower was influenced by its performance concerning the wind as seen in both its orientation and shapping. It is known that there were many tests that the building went through and they included tunnel tests and design iterations that helped in the development of optimum performance. The building also has an exterior cladding which is comprised of the aluminum and textured stainless steel spandrel panels which were explicitly designed to withstand the extreme temperatures in Dubai during the summer months. This could be effected through the use of a low-E glass which provides an enhanced thermal insulation. The building also has vertical polished stainless steel fins that were added to accentuate the slenderness and height. Its structural system, in this case, is called “buttressed core” which was designed so that it can efficiently support the supertall building through the utilization of a strong central core that was buttressed by its three wings. The tower has an efficient system at which all the building’s vertical structure is used to support both lateral loads and gravity. The tower has several enhancements to the fire and life safety systems which include lifeboat operation for the elevators which allows the use of controlled evacuation under some situations hence decreasing the evacuation time by 45% over the stairs. The height of the building generates a substantial stack effect because of its thermal differences between the building’s interior and exterior, but in this case, Burj Khalifa was explicitly designed to passively control these forces, therefore, reducing the need for mechanical means of pressurization. The management of the tower system utilizes a condense discharge which prevents it from entering the wastewater stream which reduces the need for municipal water. There are installations of own electric energy which monitors the system to enable optimization of the tower system over its lifetime. The uppermost interior floors were explicitly designed to reflect the celestial influences. The sculpture is known to have been completed by Jaume Plensa and is composed of 196 cymbals that supported by stainless steel rods that arise from two pools that are similar to reeds in a lake.
The Eiffel tower is named as the trademark of Paris, France and it has 984ft. In it, there is a restaurant, Television, and a radio station. It was created by Gustave A. Eiffel and was made of wrought iron with a medium wind resistance. It was built and completed in 1910. Its lower section consists of the four large arched legs set on the mansionary piers. The legs are seen to curve inward until they unite in a single tapered tower. Inside the building, there are platforms that have the observation deck, and the three levels contain the restaurant. The tower used about 7000 tons of iron, and it has stair and elevators. The design of the building was initially an idea of Maurice Koechlin, and it consists of the four lattice girders that stand apart at the base as they come together at the top and are joined together by the metal trusses at regular intervals. The foundation was designed to hold a load of about 10000 tons (Boske, 2013). Because of the weak soil in France, the building has two system foundation. The caissons the north and west pillars of the tower were close to the Seine river. These cause a severe problem with the infrastructure and hence the named for a stable soil. This contributed to the use of casings which gave the engineers hope to take up the challenge as they avoided the water leaks while reinforcing the foundations through the adding of concrete and brickwork.
Eiffel base has four legs with two anchor bolts that are 26 feet long each and 4 inches regarding diameter. The foundation has a placement of hydraulic jack that enables the rising or the lowering of the platform so that the building can make a certain level. There is also an erecting metal work, and it is designed in a way that the top tower shifts away from the sun by up to 18 cm due to its thermal expansion of the metal on the side view below the tower. The building is known to have the vertical transports three lifts that takes people to the 1st and 2nd floor, but it's designed that is one wants to go to the last level, there must be a change of lifts. The tower maintenance includes 50 to 60 tonnes of paint every seven years, to protect the rest. The tower height varies from 15 cm because of temperature.
Comparison of the two Towers
When comparing the two towers that are known to be among the world’s best, Burj Khalifa has a deck height of 555m while Eiffel Tower has 276.1m as both of them were built in different years and they both shined at those moments. Burj Khalifa uses a Skyscraper deck while Eiffel Tower uses Steel truss tower. Burk Khalifa is twice as tall as the Eiffel Tower, but it was built later, after the Eiffel tower becoming among the tallest building in the world. Burj Khalifa in Dubai while Eiffel Tower was built in Paris, both buildings became famous due to their structural designs that were very attractive to people. Eiffel Tower became the tallest building in its years as it was built the late 1980s until Burj Khalifa was constructed which was more than twice making it the tallest and modest building in the world.
In conclusion, the buildings were famous and modern built depending on the time they were constructed as we find that Eiffel was anciently created when there was less technology development as compared to Burj Khalifa. It was built recently with the technology development, making it modern and more attractive since it accommodates all the technologies for the contemporary world, hence making it the best and the largest in the world.
