In an attempt to prevent the landmark from collapsing, the Leaning Tower of Pisa was stabilized in the 1990s through a huge technical operation. In reality, by the end of the 1980s, the skyscraper was on its way to a catastrophic collapse.
The problem was that the base of the tower was not strong enough to support its weight. The solution used large quantities of cement and steel beams to reinforce it instead. The work was done under the supervision of Giorgio Francia, who also designed the American Bandstand.
However, despite the efforts made, the tower continues to lean at a rate of about five centimeters per year.
This is because the reinforcement process had two drawbacks: on the one hand, it reduced the volume of the base of the tower and thus increased its stability problem since the same amount of material was now using more space; on the other hand, it made the tower look even worse since now it had another reason to be leaning towards one side.
In conclusion, without going into detail about other problems surrounding the construction of the tower, such as difficulties in obtaining permits for repairs and modifications over the years, it can be said that the Leaning Tower of Pisa is a beautiful example of a well-designed building that just happened not to work out in practice.
The tower was stabilized as a result of restoration work completed between 1999 and 2001. Engineers placed weights on the structure's north end while removing earth from below, forcing it to sink back in that direction gradually. The Leaning Tower of Pisa still leans south, although at just 3.99 degrees. It is the only medieval monument in Europe that is not demolished.
In response to questions about the safety of the tower, the city government has published several reports over the years giving assurances that the tower is safe for visitors. In fact, the tower with its weight of nearly half a million pounds is actually more stable than when it first began to lean in 1350.
The story of the building's construction reveals much about the culture of the time. The original tower was planned by the famous architect Brunelleschi who died before it could be completed. His son went on to finish the job. Even though the tower does not match the design of its father, it is considered one of his greatest works.
Engineers have used different methods to balance the tower over time. The most common method today is to place scaffolding around the base of the tower and then secure it with ropes to the ground. An engineer monitors the movement of the tower from inside the scaffolding and uses this information to make adjustments where needed. This keeps the tower from leaning too far in one direction or another.
(Reuters) - Rome According to an expert who has been monitoring the famed Italian tourist attraction, the leaning tower of Pisa has been properly stabilized and will be safe for at least 300 years. "The tower is stable. It's not going to fall over tomorrow or even before it reaches its predicted lifetime of 150 years," said John Adams, a professor of architecture at the University of Western Ontario in London, Canada. The tower was built between 1173 and 1268 on land that was once part of a larger church site. It originally stood about 40 feet (12 meters) taller than it does today because it was rebuilt after being damaged in an earthquake in 1317. After that rebuild, the tower started to lean about 2 inches (5 cm) toward the west. Over time, the movement increased so much that by 1876, it was leaning more than 30 degrees off true north.
People have worried about the tower's stability since then, but nothing had been done about it until now. In 1995, the city of Pisa announced a $20 million plan to fix the problem by building a new foundation under the tower to stop it from leaning further. The following year, the European Union provided another $1.5 million for research into the future survival of the tower. Professor Adams helped design the new foundation system and has been monitoring its progress since it was initiated.
Fortunately for the inhabitants of Pisa, the lengthy construction delays allowed the building to settle and the earth to compress. This strengthened the foundation over time and is the major reason the tower never collapsed. The tower has been crumbling for hundreds of years.
The Pisa tower is a good example of how natural forces can be used beneficially to strengthen buildings. If it weren't for this effect, many large structures built during medieval times would have been unable to support themselves.
The Pisa tower was not the only one being built at the time. There were similar towers being constructed all over Europe. Some historians believe that this competition caused more projects than they knew what to do with, which caused costs to increase without corresponding gains in strength. The Pisa tower was also built using different techniques than other European towers of its time. It is estimated that about 17 million bricks were used in its construction. Bricks made at that time were not as strong as those today so the Pisa tower would have failed early if it were being built today.
In conclusion, the Pisa tower was not built quickly or easily, but rather came at a cost that no one wanted to pay. If it weren't for the fact that it had become important political territory between France and Italy, it probably wouldn't exist today.
There were four fatalities. The Leaning Tower of Pisa was closed down by Italian authorities the following year. People were no longer allowed to walk all the way to the top. An multinational team of building specialists launched an initiative to ensure the leaning skyscraper did not collapse. They designed a new platform for the tower's base and reopened the viewing gallery in 1998.
In addition to the visitors injured when it collapsed in 1178, there had been at least two other deaths on the tower before its renovation. In 1256, someone opened up a window on the second floor of the tower and threw themselves out. In 1854, an engineer repairing one of the windows fell to his death.
The Leaning Tower of Pisa has been called Europe's most photographed sight. Over 30 million people have seen it since it became famous worldwide in 1436. That makes it the most viewed monument in Italy and the third most visited tourist attraction in Europe after the Eiffel Tower in Paris and the Statue of Liberty in New York.
The tower has been undergoing renovations since 1990. As of February 2016, it is expected to be completed in 2017.
In conclusion, there were four deaths during the construction of the Leaning Tower of Pisa in the 14th century.
