It caused more than 8500 casualties and left over 22000 people injured. Another major earthquake of magnitude 7.3 occurred in Nepal on May 12, 2015. Thousands of buildings were destroyed and many more rendered unsafe.&lt;/p&gt; &lt;p&gt;Detailed surveys and inspections of reinforced concrete structures affected by the earthquakes in Nepal were conducted in a reconnaissance effort funded by The American Concrete Institute. The effort was concentrated on identification of buildings with structures similar to new and older reinforced concrete buildings in seismic areas in the U.S. The reconnaissance group consisted of 4 teams (A, B, C and D) with 3 or 4 people in each team. Data were collected between June 18, 2015 and July 01, 2015.&lt;/p&gt; &lt;table&gt; &lt;tr&gt; &lt;td &gt;&lt;a href="/app/site/resources/2015/07/00242/high1-1.JPG" target="_blank"&gt; &lt;img class="contentimg" src="/app/site/resources/2015/07/00242/high1.jpg" height="350" alt="image" /&gt;&lt;/a&gt;&lt;/td&gt; &lt;td &gt;&lt;a href="/app/site/resources/2015/07/00242/high2-1.JPG" target="_blank"&gt; &lt;img class="contentimg" src="/app/site/resources/2015/07/00242/high2.jpg" height="350" alt="image" /&gt; &lt;/a&gt;&lt;/td&gt; &lt;td &gt; &lt;a href="/app/site/resources/2015/07/00242/high3-1.JPG" target="_blank"&gt; &lt;img class="contentimg" src="/app/site/resources/2015/07/00242/high3.jpg" height="350" alt="image" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;br/&gt;&lt;br/&gt; &lt;center&gt; &lt;img class="contentimg" src="/app/site/resources/2015/07/00242/ACI_Logo.jpg" width = "320" alt="image" /&gt; &lt;/center&gt; &lt;br/&gt;&lt;br/&gt; &lt;div&gt; This database contains information on 30 high-rise reinforced concrete buildings with 8 to 17 stories above ground. Building plans, drawings, photographs and GPS coordinates were collected for buildings that were inspected. Structural drawings and models were also collected for some of the inspected buildings. &lt;br/&gt;&lt;br/&gt; &lt;table&gt; &lt;tr&gt; &lt;td width="50%"&gt; &lt;a href="/app/site/resources/2015/07/00242/map-1.png" target="_blank"&gt; &lt;img alt="image" class="contentimg" src="/app/site/resources/2015/07/00242/map.png" style="float: left; width: 500px" target="_blank" /&gt; &lt;/a&gt; &lt;/td&gt; &lt;td width="50%" &gt; Locations where photographs were taken has been annotated on the drawings and building plans provided. For example, photograph name IMG_0038 corresponds to location 38 shown on the drawing/building plan.
