Database of low-rise reinforced concrete buildings with earthquake damage

<table> <tbody> <tr> <td width="60%"> <a href="/app/site/resources/2015/01/00100/N4.jpg"> <img alt="image" src="/app/site/resources/2015/01/00100/N4.jpg" wdith="400" /></a></td> <td width="40%">This database contains building information of 616 low-rise reinforced concrete buildings with earthquake damage collected during seismic vulnerability assessment from 6 different earthquakes (Erzincan 1992, Duzce 1999, Bingol 2003, Peru 2007, Wenchuan 2008, and Haiti 2010). With a goal to evaluate the Priority Index proposed by Hassan and Sozen (1997), the reconnaissance team from 6 different earthquakes collected a total number of 7,044 photographs of 616 structures which were constructed with reinforced concrete or concrete masonry units.</td> </tr> </tbody> </table> <p> </p> <p>This database is presented as a spreadsheet with each row containing the following information of a building:</p> <ol> <li>Title: Title of the project, group of experiments, simulations or surveys</li> <li>Source: Names of the people who generated the data</li> <li>Keywords: Words describing the dataset, which can be used for searching</li> <li>Report(s): Related documentation</li> <li>Experiment or Case ID: ID assigned by the source to the sample, specimen, case, survey, site, experiment or simulation</li> <li>Latitude: Latitude of the location where data was collected, if applicable</li> <li>Longitude: Longitude of the location where data was collected, if applicable</li> <li>Parameters: Variables and parameters chosen by the researcher, compiler, professional or scientific organization to describe the data</li> <li>Drawings/Diagrams: Drawing and diagram files needed to interpret the data</li> <li>Data: Data files generated through project.
