Quantifying the Post-Earthquake Downtime Induced by Cordons around Damaged Tall Buildings

After an earthquake, individual buildings may be unusable for a long time while waiting for repairs. However, Christchurch, New Zealand’s earthquake in 2011 demonstrated that even undamaged buildings could experience downtime if there is concern that nearby, heavily damaged buildings may collapse in an aftershock. This talk will present a framework for assessing the additional downtime induced by the access restrictions associated with safety barricades (or “cordons”) around damaged tall buildings. Downtown San Francisco will be presented as a case study for how to collect and incorporate real-world data at scale. Though still preliminary, this example demonstrates what is possible and how the results could inform policy decisions that focus on community resilience.
