Progressive Destruction of Frame Buildings Made of Monolithic Reinforced Concrete

The design of multi-storey buildings is currently carried out with mandatory verification of their progressive destruction. Progressive destruction is the process of rapid sequential destruction of load-bearing structures due to the destruction of any element of the building or part of it. Different factors can be the causes of local destruction: an explosion of household gas, terrorist acts, the impact of vehicles on the supporting structures of the building, the impact of wind loads that exceed the amount accepted in the project, and so on. The article investigates possible scenarios for the occurrence of a progressive destruction due to a car hitting one of the columns along the perimeter of a multi-storey frame building. Options were considered for a car hitting a row column located in the middle of the building, as well as a car hitting one of the corner columns. It was found that the impact of a car hitting an ordinary column leads to its destruction, as well as the destruction of the building ceiling above the first floor. The most dangerous option is the car hitting the corner column. A hit to the corner column causes the corner of the building to collapse globally.
