Assessing building habitability after an Earthquake. Application in Lorca, Spain.
Most methodologies used to rate building vulnerability after a seismic event analyze building performance based on structure and construction, without taking other factors into account. Some recent empirical methodologies have introduced urban design parameters that can make buildings more or less vulnerable to seismic events, depending on the location of the building and other factors that can condition building behavior during an earthquake (irregular plan or vertical irregularity, the difference in height compared to adjoining buildings, etc.). Design parameters that affect the seismic vulnerability of buildings are referred to in the present study as "urban modifiers." The present study proposes a statistical methodology that may be used to rate the habitability of different types of buildings after an earthquake. The first step was to rank variables that affect the vulnerability of a building and formulate a statistical study with a discrimination index that makes it possible to identify buildings as habitable or non-habitable. This ranking applied the criteria established in various international guidelines—most of which are based on documentation generated by the ATC-Applied Technology Council— that are used to distinguish between habitable (undamaged—no structural damage) and non-habitable buildings (structural damage). The same methodology was applied to a database with information about buildings and the extent of damage experienced following the 2011 earthquake in Lorca. The results obtained will be beneficial in helping to plan for an emergency both before and after an event by making it easier to identify non-habitable buildings and estimate the number of people that would need to be rehoused in different public buildings (schools, sports centers, etc.) or emergency camps.
