Abstract: Progressive collapse of a building occurs when the actions on the resistance structure or boundary conditions are changed so that some components are loaded beyond their bearing and collapse. The remainder of the structure needs to create a redistribution of inner forces to take external loads. As a result of this redistribution, other elements may collapse, causing the structure redistribution process to continue until either external loads cannot act because the structure collapse, or find an alternative structure stable equilibrium. The initial causes that can lead to a progressive collapse are multiple and often based on an event are several causes combined. This can include violent change of air pressure (accumulation of gas explosion, bomb attacks, tornadoes) controlled explosion, earthquake, fire, impact of vehicles, weather conditions (snow, frost, wind), agglomerations of people, design mistakes , execution errors.
