Seen here is a collapsed building in the capital city Port-au-Prince of Haiti following the January 2010 earthquake. It appears to have been a soft story collapse seeing the entire roof structure is mostly intact. Possible explanations of this could be weak concrete used in the columns or possibly too little steel reinforcement. Seeing this building was built in Haiti, lower construction quality is likely compared to countries like the United States, and lower code requirements exist, which unfortunately lead to a weaker building more susceptible to collapse.
