Facilities (EF) are jointly hosting a user workshop on May 17, 2018. A live
demonstration test is planned for this workshop to showcase the capabilities of
each facility as well as the complementary nature of the two EFs. To fulfill
their commitment to community outreach activities that promote science, technology,
engineering and mathematics (STEM), the NHERI WOW and RAPID EFs are
broadcasting this demonstration live. </p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><span style="font-size:11pt">If you are interested in watching this

<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif">A large-scale model building will be exposed to
hurricane-force winds to assess the performance of roofing and cladding
materials in such extreme wind events. The building is of wood-frame construction
with exterior plywood walls covered by vinyl siding. Internally, the building
is finished with 1/2” drywall painted with white primer. The gabled-roof of the
building is covered with asphalt shingles. There are two single-hung windows in
place among which one is impact-rated. The model building is anchored to the 16
ft diameter turntable at the Wall of Wind Experimental Facility.</p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><b>Procedure:<span style="color:black"><span></span></span></b></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><u><span style="color:black">Pre-testing
activities:</span></u><span style="color:black"> The
drywall interior will have been wetted in a distinct pattern two days prior to
testing. One day prior to testing, the RAPID team will complete a baseline
pre-scan of the structure exterior using the Leica BLK360, a portable terrestrial
lidar scanner. A thermal imaging scan of the interior will be captured using
the BLK360 and the Flir Pro One to detect interior drywall wetting. <span></span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><u><span style="color:black">Testing
activities (live demonstration):</span></u><span style="color:black"> The wind speed will increase gradually and the turntable will re-orient
to alter the approach wind direction. Rain droplets will be added to the flow
to improve flow visualization and create potential wind-driven rain water
intrusion. <span></span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><u><span style="color:black">Post-testing
activities:</span></u><span style="color:black"> Upon
completion of the wind testing, damage to the building cladding and roof will
be visually inspected. The RAPID team will conduct a post-scan with the BLK360 lidar
to quantify physical exterior damage. A thermal scan will be conducted with the
BLK360 and Flir Pro One on the interior to detect wind-driven rain water
intrusion. Post processing of the lidar scans will be conducted in the
afternoon. Remote live broadcast viewers will be able to access a presentation
of results on DesignSafe.<span> </span><span> </span><span></span></span></p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><span style="color:black"><span><br></span></span></p><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><img src="cid:ii_jfiza36b0_16289186ab492644" width="270" height="63" class="m_321175099113625324m_-2114360263270446144gmail-CToWUd m_321175099113625324CToWUd" style="margin-right:0px"><img src="cid:ii_jfizah031_1628918b16c93806" width="267" height="65" class="m_321175099113625324m_-2114360263270446144gmail-CToWUd m_321175099113625324CToWUd" style="margin-right:0px"><span style="color:black"><span><br><br></span></span></p>
