Classification of Collapsed Buildings for Fast Damage and Loss Assessment

Schweier, Christine; Markus, Michael

Fast and reliable identification of collapsed buildings is essential in case of earthquake disasters in urban areas. Airborne laserscanning offers the possibility to fulfil this task. Based on height measurements, geometrical surface models of buildings can be generated with this technology. Comparing the undamaged pre-event models with those recorded after an earthquake, the location of collapsed buildings and the dimension and characteristic of their damage can be obtained. The knowledge about typical damage types of collapsed buildings is necessary to interpret the changes found between the pre- and post event building models. As existing building damage classifications don�t meet the requirements of this novel technique, observations and reports of building collapses were analysed. This leads to a new classification system of collapsed buildings and the definition of the so-called �damage catalogue�.

The damage catalogue is a composition of different damage types of entire buildings typically oc-curring after earthquakes and it contains the observed dimensions of the geometrical features such ... mehr
