8、y .16IntroductionWhat would Paris be without the Eiffel Tower,or London without its famous clock tower,Big Ben?Iconic structures such as these,along with surrounding buildings,create an outline against the sky,called a skyline.Skylines are unique identifiers of places,just as your fingerprints are o

9、ne-of-a-kind identifiers of you.Unlike fingerprints,however,skylines dont stay the same forever.They grow and change,sometimes gradually and at other times quite suddenly.New York City is a great example of a place whose skyline has experienced both slow and rapid change.In recent years,New Yorks sk

10、yline has been altered dramatically.Buildings and structures have risen,fallen,and risen again.New Yorks skyline has continuously evolved.LondonParisNew YorkA New Skyline Level W56Growing the Big AppleDuring the nineteenth century,New York Citys famous skyline,along with its diverse population,began

11、 to grow rapidly.With the end of the Civil War came freed slaves from the South in search of work.Later,waves of Europeans immigrated to the United States through the port of New York.Many of them stayed on New Yorks Manhattan Island.By the late 1800s,New York was the most densely populated city in

12、the country;by 1925,it was the most densely populated city in the world.All the citys new residents needed places to live,work,and shop.Gradually,the city expanded northward as more stores,factories,and homes were built.However,Manhattan Island is only about 23 square miles(59.6 sq km)in area.There

13、was no more room for the city to expand outward;the only place to grow was up.To do that,new building methods had to be employed.Up until that time,walls had been used to support a buildings weight.The walls on a buildings ground floor had to be strong enough to bear the weight of all the floors and

14、 the roof above them.This type of construction limited a buildings height.There was no practical way to make walls thick and strong enough to support a building with dozens of floors.A new way of building involved using a steel frame instead of walls to support the structure.Gigantic steel beams wer

15、e connected to form the buildings skeleton.Then the walls were hung from the beams,much like curtains from a rod,and attached at the bottom to the floor.With the use of steel frame construction,the walls of the buildings upper floors were not weighing heavily on the lower floors walls.The weight of

16、the walls was distributed along the steel beams holding them up.Steel frame construction made it possible for buildings to reach new heights.By the turn of the twentieth century,New York City housed a number of huge structures that came to be called skyscrapers.Soon skyscrapers were going up one aft

17、er another as builders and architects competed to make the worlds tallest building.An 1884 illustration of Lower Manhattan Island shows how little of the citys structure and skyline was developed at the time.A New Skyline Level W78Building an EmpireBy the late 1920s,New York Citys skyline had risen

18、to new heights.It was during this time that two of the citys best-known structures were built.In 1928,the builder of the seventy-seven-story Chrysler Building wanted to make it the worlds tallest.So fierce was the competition for this title that the Chrysler builder smuggled a tall spire onto the to

19、p of his structure.The secret plan worked:in 1930,the Chrysler Building became not only the worlds tallest structure but also the only one to stand taller than 1,000 feet(305 m).The Chrysler Buildings reign would not last.Just blocks away,a steel-framed behemoth was rising.Not only would the Empire

20、State Building take the crown for worlds tallest,but it would also come to define the city it called home.The Chrysler Building was funded by businessman Walter Chrysler.Buildings of the New York City Skyline1 1899 Park Row Building 391 feet(119 m)29 stories2 1908 Singer Building 612 feet(186.5 m)37

23、m)tall.More than 3,000 workers contributed skills and labor to finish the building.The completed building had 64 working elevators that took less than one minute to get to the 80th floor.An outside observation deck on the 86th floor and an inside deck on the 102nd floor provided panoramic views of t

24、he city.The Empire State Building symbolized New York City.It was named one of the Seven Wonders of the Modern World and was featured in many books and movies.It wore the crown of worlds tallest building for nearly forty years until deposed by twin giants rising in the lower part of Manhattan.Twin G

25、iants Rise,Then FallAfter the Empire State Building was completed,skyscraper construction slowed down.Mammoth structures were costly to build,and the American economy was struggling.It was not until 1970 that the citys skyline would grow even higher.In the 1960s,city officials considered building a“

26、world trade center”a hub for international commercein Lower Manhattan.The Port Authority of New York and New Jersey was in charge of the project.Architect Minoru Yamasaki designed the buildings.He proposed twin towers as part of the multibuilding complex of offices and storefronts.The 110-story towe

27、rs would include some structural innovations.The Port AuthorityThe Port Authority of New York and New Jersey is an organization formed in 1921.Its purpose was to develop,modernize,and operate trade and transportation facilities in both New Jersey and New York City.The Port Authority still owns and m

29、ew Skyline Level W1112One innovation was the use of tube-frame construction instead of steel-frame construction.Each tower was similar to a hollow square pipe.The outside perimeter of the building had columns that were spaced close together.Surrounding the edge of the building with main support colu

30、mns created more usable floor space inside.Another innovation was the use of sky lobbies.The taller a building is,the more elevators it needs.Yamasaki proposed an elevator system modeled after the citys subway system.The towers had both express and local elevators.People could take an express elevat

31、or to a sky lobby on the forty-fourth floor that would bypass the first forty-three floors.Then they would transfer to a local elevator,which would stop at every floor,to get to their office on the forty-eighth floor.This system was a new,efficient way to transport people vertically,and it reduced t

32、he number of elevator shafts needed.Construction of the towers began in 1966.The North Tower was completed in December 1970,topping out at 1,727 feet(526 m)at the top of its spire.A restaurant called Windows on the World offered diners a breathtaking view from the top of the North Tower.The South To

33、wer,reaching 1,362 feet(415 m)in height,was finished seven months later.Beneath both buildings was a parking garage that could accommodate up to two thousand vehicles.Railroad and subway stations were situated underneath the parking garage.Over 3,500 workers helped build the World Trade Centers twin

34、 towers during their peak of construction.Who Was Elisha Otis?How were people supposed to get to the top floors of a skyscraper?Climbing hundreds of stairs wasnt a good optionelevators were needed.Early elevators,however,werent as safe as they should have been.Thanks to Elisha Otis,this problem was

35、resolved.Otis designed the first safety elevator in 1854.The elevators platform would fall only a few inches if the cable holding it broke.He also designed engines to power the elevator.Without a doubt,Otiss invention was necessary to the development of tall buildings.The next time youre in an eleva

36、tor,look around.Theres a good chance youll see the name“Otis”somewhere inside!Elisha Graves OtisA New Skyline Level W1314The Twin Towers were a striking addition to the citys skyline.Because they were built away from the citys other tall skyscrapers,they dwarfed the surrounding buildings and were th

37、e most prominent structures on Manhattan Island.For thirty years,the World Trade Center towers were the tallest buildings in New York.Then disaster struck.On the morning of September 11,2001,hijackers flew two passenger jets into the towers.Within an hour after the attack,the South Tower began to fa

38、ll in on itself and crumble to the ground.The North Tower followed thirty minutes later.New Yorkers watched in stunned disbelief as these enormous structures were reduced to heaps of burning rubble.Nearly three thousand people died as a result of the attack.A New Tower Rises from the AshesThe World

39、Trade Center tragedy devastated New York and the rest of the country.New Yorkers mourned the loss of their neighbors and their landmark.At the same time,they vowed to rebuild at the World Trade Center site.Excavating the ruins of the old towers took time.Plans for the site took years to develop;ther

40、e were many opinions on what should be done,and many designs were submitted with considerable controversy.Finally,the Port Authority unveiled the design for the new World Trade Center complex.One area was set aside as a memorial park for those who lost their lives that day.The sites where the origin

41、al buildings stood are now reflecting pools with cascading waterfalls.A memorial museum contains items from the old towers.On September 11,2001,terrorists flew two planes into the Twin Towers.One of the two reflecting pools at the World Trade Center Memorial.Both feature the largest human-made water

43、agon shape,and its huge reflective surface mirrors the changes in light all around it.At the top is a spire equipped with a light beam that is visible for miles.Several other high-rises are being constructed at the site as well.By the year 2020,the new World Trade Center complex should be complete.N
