| | 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. |
