SYSTEM WOULD HELP HAITI BUILD, MODIFY EARTHQUAKE-PRONE STRUCTURES. - 0 views

Civil engineers studying the effects of Haiti's devastating earthquake have concluded that a relatively simple system could be used by officials to quickly decide how to modify existing buildings and construct new ones that would better withstand future quakes.

The system represents a practical method to improve the earthquake resistance of buildings

About 40 percent of the buildings were heavily damaged, and findings showed that about 90 percent of those damaged structures would have been classified as vulnerable if the system had been in use.

Research Question: Still today, what are the social, economical, and political effects of the earthquake in Haiti? Citation Source: "SYSTEM WOULD HELP HAITI BUILD, MODIFY EARTHQUAKE-PRONE STRUCTURES." States News Service 19 Oct. 2010. Academic OneFile. Web. 16 Feb. 2011. Summary: This Article is about engineers studying the effects of Haiti's terrible earthquake. They tell us that if the people had constructed their buildings differently, many would not have been destroyed so dramatically. The engineers have found a system to improve the earthquake resistance of buildings. Out of 170 damaged buildings surveyed in January, 40% were heavily damaged, and 90% of those buildings would have been vulnerable if the system was in place. The Article goes on to tell us that for a certain sized building, the smaller the columns and fewer the walls between the columns, the more damaged the building will be. They discovered that most homes in Haiti had these "captive columns." This is were a wall is attached to a column, but does not extend as tall as the column, leaving a portion unsupported. It tells us around 60% of the 170 buildings had captive columns. However, the engineers have decided to follow the system to help reinforced concrete buildings today.
