Tall Buildings Video – AE 221 Homework #1 (HW1)

  1. List three (3) inventions that advanced the increased height of tall buildings.
         One of the most important discoveries in the development of tall buildings was the
          invention of steel by Henry Bessemer. By smelting iron ore with carbon the
          product was a much stronger and flexible material which allowed buildings to be
          built taller and sustain greater loads.
         Mechanical inventions such as air conditioning and lighting also made it possible
          for buildings to be built higher. With the invention of air conditioning and
          lighting, rooms no longer had to be on the perimeter of the building. Skyscraper
          architects no longer had to depend on the outside breeze and light to make the
          room comfortable.
         The invention of the elevator was a crucial milestone in the advancement of tall
          buildings. As buildings grew taller, the prospect of traversing tens of flights of
          stairs became a deterrent for skyscraper living. The elevator provided a much
          more efficient and less tiresome means of traveling up and down a skyscraper.

  2. Which exterior wall system will construct the taller building? (concrete or brick)

            Concrete will serve as the better exterior wall system. Concrete is much better at
     handling compression than brick is. To compensate for this fact, a tall building with
     brick as its exterior wall system will have to have a very thick wall at the base; the higher
     building, the thicker the base.

  3. List three (3) limitations or complexities for constructing future taller buildings.

         One complexity that will need to be dealt with, as buildings continue to grow, is
          the wind. Different parts of the buildings may experience different strengths and
          directions of wind depending on how high the building is.
         Another limitation, of course, would be budget. Skyscrapers tend to get
          exponentially more expensive the higher they get.
         Lastly, a significant limitation on the height of skyscrapers is the amount of
          required elevators. Elevators take up a large area of a building and the higher the
          building, the more elevators will be necessary.

  4. List the three (3) categories for measuring tall building as stated by
     the Council on Tall Buildings and Urban Habitat
       Highest Occupied Floor
       Height to the top of the roof
       Height to the top of any spire or antenna



5. List the tallest three (3) buildings in the US that are built or under construction, not only
   designed):
       The Willis Tower (formerly Sears Tower) is in Chicago, Illinois and has 110
        floors. The roof is 442.1 meters tall and the highest roof deck is 436.5 meters tall,
        but antenna included, the building is 527.3 meters tall.
       One World Trade Center, also known as Freedom Tower is under construction in
        New York, New York and will be 82 floors tall. The finished height of the
        building will be 417 meters (which is the same height as World Trade Center
        Buildings). The height of the highest occupied floor is 400.5 meters. The added
        spire will make the building 541.3 meters (1776 ft.)
       The Empire State Building is in New York, New York and has 102 floors and is
        381 meters (1250 ft.) tall. The highest occupied floor is 373.2 meters high and the
        height including the antenna is 443.2 meters tall.

6. List the ten (10 tallest buildings - built or under construction) in the World, include:
       The Burj Khalifa is in Dubai, United Arab Emerites and has 163 floors. The
        highest occupied floor of the building is 584 meters whereas the roof is 628 meters
        tall. With the spire included, the building is a staggering 828 meters tall.
       The Shanghai Tower is in the Pudong district in Shanghai, China. This building is
        128 floors high and is still under construction, to be completed in 2014. The
        proposed height of the building will be 632 meters.
       The Makkah Royal Clock Tower Hotel will be 95 floors high and is being built in
        Mecca, Saudi Arabia. The proposed height of the building including the spire will
        be 601 meters.
       One World Trade Center, also known as Freedom Tower is under construction in
        New York, New York and will be 82 floors tall. The finished height of the
        building will be 417 meters (which is the same height as World Trade Center
        Buildings). The height of the highest occupied floor is 400.5 meters. The added
        spire will make the building 541.3 meters (1776 ft.)
       Busan Lotte Tower is located in Busan, South Korea and will be 110 floors high.
        The Busan Lotte Tower is under construction and is expected to be 510.2 meters to
        the top of the roof and has no spire.
 Taipei 101is a 101 floor skyscraper in Taipei, Taiwan. The highest occupied floor
  of the building is 438 meters high whereas the top of the roof is 10 meters higher at
  448 meters tall. With the spire included, the height of the building is 508 meters
  tall.
 The Shanghai World Financial Center has 101 floors and is located in Shanghai,
  China. The top occupied floor of the building stands 474 meters high. The roof is
  492 meters high and the building does not have a spire or antenna.
 The International Commerce Center is in Hong Kong, China and has 108floors.
  The main roof deck is 470.6 meters high, while the height to the top of the roof is
  484 meters. The International Commerce Center does not have any antennas or
  spires.
 The Petronas Towers are in Kuala Lumpur, Malaysia and stand 88 floors high. The
  highest occupied floor is 375 meters high and the top of the roof is slightly higher
  at 378.6 meters high. With the spire(s) included, the building is 451.9 meters tall.
 The Nanjing Greenland Financial Complex is 89 floors tall and is located in
  Nanjing, China. The highest occupied floor of the building is 339 meters high and
  the roof is 381 meters tall. When including the spire, the top of the building is 450
  meters high.
