Disasters and Collapses - How and Why Buildings Fall Down
Despite the best laid plans of architects and engineers, great buildings can fall. Some are destroyed by earthquakes, fires, floods, and other natural disasters. Some structures are destroyed by deliberate acts such as the terrorist attacks on New York's World Trade Center. Finally, faulty design can lead to structural collapse. Explore these links to explore how and why some buildings fall.

Did The Building Do It?
A comprehensive study from a professor working under a grant from the National Science Foundation suggests that the design of the World Trade Center buildings may have lead to their collapse during the September 2001 terrorist attacks.

Why Did the Charles-de-Gaulle Airport Terminal Collapse?
When it opened in 2003, many people praised the futuristic structure, calling it both beautiful and practical. Since there were no internal roof supports, passengers could move easily through the terminal. Was the innovative design partly responsible for the terminal's fatal collapse?
