Post-earthquake building assessments

Major seismic events occurring around urban centres often cause widespread damage to the building stock. Engineers are then required perform safety inspections of these buildings. This process may be time-consuming and can residents or businesses displaced for a considerable duration even if is safe occupy. Furthermore, other post-earthquake recovery phases, such as repair demolition/reconstruction works, not initiate until inspection phase complete. As such, disruptions caused by need considered when modelling occupancy/functionality downtime. study uses data obtained from 2011 Christchurch earthquake develop quantification model. Firstly, rapid assessment estimated number damaged buildings assessed, total available engineers, median time needed assessing each building. Secondly, probability being assigned certain colour tag (White, Yellow Red) derived based on extent damage. Finally, both sets information combined quantify duration. A case examined demonstrate application proposed
