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.&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;p&gt; &lt;/p&gt; &lt;p&gt;This database is presented as a spreadsheet with each row containing the following information of a building:&lt;/p&gt; &lt;ol&gt; &lt;li&gt;Title: Title of the project, group of experiments, simulations or surveys&lt;/li&gt; &lt;li&gt;Source: Names of the people who generated the data&lt;/li&gt; &lt;li&gt;Keywords: Words describing the dataset, which can be used for searching&lt;/li&gt; &lt;li&gt;Report(s): Related documentation&lt;/li&gt; &lt;li&gt;Experiment or Case ID: ID assigned by the source to the sample, specimen, case, survey, site, experiment or simulation&lt;/li&gt; &lt;li&gt;Latitude: Latitude of the location where data was collected, if applicable&lt;/li&gt; &lt;li&gt;Longitude: Longitude of the location where data was collected, if applicable&lt;/li&gt; &lt;li&gt;Parameters: Variables and parameters chosen by the researcher, compiler, professional or scientific organization to describe the data&lt;/li&gt; &lt;li&gt;Drawings/Diagrams: Drawing and diagram files needed to interpret the data&lt;/li&gt; &lt;li&gt;Data: Data files generated through project. Tabular text format is preferred (e.g., *.txt, *.csv).&lt;br /&gt; It is recommended that data files are organized in columns with each column having a descriptive header (e.g., sensor ID and unit)&lt;/li&gt; &lt;li&gt;Photos, Videos, etc.: Media files including photos, videos, audio generated through project&lt;/li&gt; &lt;li&gt;Compiled by: Names of the people who compiled the data&lt;/li&gt; &lt;li&gt;Date: Date when the dataset was compiled.
