 Summary:
 Progressive collapse is collapse of the whole structure or large part of it, initiated by failure of one or more structural elements or part of the structure. Such failure or damage of one structural element or part of it initiates chain reaction, comparable to domino effect and failure of other structural damages resulting in total collapse of the structure. This effect is characteristic for high–rise structures. The structure is supposed to receive and transfer all actions to the building to the load bearing soil. In majority of cases, permanent actions are predictable. Service variable loads are usually defined through national codes. However, it is not simple issue to reliably predict lateral loads, such as wind and seismic actions to the buildings. When discuss the lateral actions, their effects are major factors for high–rise structures. Lateral actions, such as wind and seismic actions increase with buildings’ height and become main problem which may make building unstable, unusable, with the critical case scenario of building’s collapse or over turning. The issue with accidental actions and their effects to the buildings is even more complex. Accidental actions include blasts such as explosions, detonations and bombs etc., impacts which take vehicle into consideration such as aircraft impact etc. Fire has been a main problem for construction, since the beginnings of the first more complex buildings and structures. Such accidental actions are not commonly treated and considered within structural design, so they deserve a special attention in consideration of progressive collapse of high-rise buildings as this is the case with lateral.
