The test specimens consisted of either RieberLok Gasketed or Diamond Lok-21 pipe with a restraining ring. Tests provided measures of axial displacement capacity, pipeline connection strength, and failure mechanism. The results indicated these systems as potentially viable solutions for regions prone to persistent soil movement and settlement. Tests were conducted in partnership with Denver Water.</p><p>Failed specimen after testing in tension.</p><p><strong>View the full report </strong><a href="/center/ciest/media/9" rel="nofollow"><strong>here</strong></a><strong>.</strong></p></div> </div> <div class="ucb-article-content-media ucb-article-content-media-right col-lg"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="imageMediaStyle large_image_style"> <img loading="lazy" src="/center/ciest/sites/default/files/styles/large_image_style/public/article-image/dwpt17.png?itok=pVRd0B06" width="1500" height="522" alt="Denver water axial tension test specimen set up."> </div> </div> </div> </div> </div> </div> </div> </div> </div> <h2> <div class="paragraph paragraph--type--ucb-related-articles-block paragraph--view-mode--default"> <div>Off</div> </div> </h2> <div>Traditional</div> <div>0</div> <div>On</div> <div>White</div> Wed, 30 Sep 2020 06:00:00 +0000 Anonymous 229 at /center/ciest Evaluation of Hazard-Resistant Pipelines /center/ciest/2019/09/27/evaluation-hazard-resistant-pipelines <span>Evaluation of Hazard-Resistant Pipelines</span> <span><span>Anonymous (not verified)</span></span> <span><time datetime="2019-09-27T00:00:00-06:00" title="Friday, September 27, 2019 - 00:00">Fri, 09/27/2019 - 00:00</time> </span> <div> <div class="imageMediaStyle focal_image_wide"> <img loading="lazy" src="/center/ciest/sites/default/files/styles/focal_image_wide/public/article-thumbnail/load_frame.jpg?h=7e51bf05&amp;itok=ApuD-hJs" width="1200" height="800" alt="load_frame_pic"> </div> </div> <div role="contentinfo" class="container ucb-article-categories" itemprop="about"> <span class="visually-hidden">Categories:</span> <div class="ucb-article-category-icon" aria-hidden="true"> <i class="fa-solid fa-folder-open"></i> </div> <a href="/center/ciest/taxonomy/term/12"> Projects </a> </div> <div role="contentinfo" class="container ucb-article-tags" itemprop="keywords"> <span class="visually-hidden">Tags:</span> <div class="ucb-article-tag-icon" aria-hidden="true"> <i class="fa-solid fa-tags"></i> </div> <a href="/center/ciest/taxonomy/term/120" hreflang="en">Lifeline Systems</a> <a href="/center/ciest/taxonomy/term/130" hreflang="en">PVC Pipe</a> <a href="/center/ciest/taxonomy/term/117" hreflang="en">Pipeline Systems</a> <a href="/center/ciest/taxonomy/term/97" hreflang="en">Reports</a> <a href="/center/ciest/taxonomy/term/14" hreflang="en">Research</a> <a href="/center/ciest/taxonomy/term/22" hreflang="en">Structures</a> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default"> <div class="ucb-article-content-media ucb-article-content-media-above"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="field_media_oembed_video"><iframe src="/center/ciest/media/oembed?url=https%3A//www.youtube.com/watch%3Fv%3D-SHb-60S5CA&amp;max_width=516&amp;max_height=350&amp;hash=wP6-LXBRwJOdL0AXLBkk0Mxpu5AMEDnJcpCjRdtKCBM" width="516" height="290" class="media-oembed-content" loading="eager" title="Transverse Loading"></iframe> </div> </div> </div> </div> </div> <div class="ucb-article-text d-flex align-items-center" itemprop="articleBody"> </div> </div> </div> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default 3"> <div class="ucb-article-row-subrow row"> <div class="ucb-article-text col-lg d-flex align-items-center" itemprop="articleBody"> <div><p><strong>Full Project Title:&nbsp;</strong>Seismic Evaluation of Hazard-Resistant Pipelines: Axial Testing of PVC, PVCO, and iPVC Pipe with Coupling</p><p><strong>Year:</strong>&nbsp;2019</p><p><strong>Industry Partners:</strong>&nbsp;East Bay Municipal Utility Department (EBMUD)</p><p><strong>CIEST Personnel:</strong> Cory Ihnotic, David Kyle Anderson, Jessica Ramos, David&nbsp;Balcells, Brice Lucero, John Hindman, and co.</p><p><strong>Primary Investigator:</strong>&nbsp;Prof. Brad Wham</p><p><strong>Summary:</strong>&nbsp;The first in a series of testing programs at CU 麻豆影院 CIEST&nbsp;investigating performance of critical lifeline systems under extreme loading conditions. This study focuses on the&nbsp;response of various thermoplastic pipe materials and a coupling connection under externally applied axial and lateral loading.&nbsp; Internally pressurized, 6 in. (150 mm) diameter specimens were tested to failure under various loading scenarios including axial tension, compression, and cyclic loading as well as transverse 4-pt bending. This project initiated&nbsp;the development of self-reacting test frame capable of applying dynamic tension and/or compressive loading in excess of&nbsp;100,000 lbs (445 kN) to linear structures up to 12 ft (3.66 m) long. CIEST鈥檚 1,000,000 lb (4450 kN) four-post load frame was employed to apply lateral loading. &nbsp;</p><p><a href="/center/ciest/sites/default/files/attached-files/2020_dw-ciest_axial_testing_c900_w_reinforced_gaskets_final.pdf" rel="nofollow"><strong>View the full report</strong></a></p><p>Appreciation is extended to collaborators David Katzev and Timothy Harris of EBMUD for their intellectual and practical contributions to the project.&nbsp;</p></div> </div> <div class="ucb-article-content-media ucb-article-content-media-right col-lg"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="imageMediaStyle large_image_style"> <img loading="lazy" src="/center/ciest/sites/default/files/styles/large_image_style/public/article-image/load_frame.jpg?itok=WWcLbGsd" width="1500" height="1124" alt="load_frame_pic"> </div> </div> </div> </div> </div> </div> </div> </div> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default"> <div class="ucb-article-content-media ucb-article-content-media-above"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="field_media_oembed_video"><iframe src="/center/ciest/media/oembed?url=https%3A//www.youtube.com/watch%3Fv%3D2WdeWlrHH-E&amp;max_width=516&amp;max_height=350&amp;hash=VfHGagxUd-haNRk31TgqkM6-DDRM-BMC8-J35OnyH3E" width="516" height="290" class="media-oembed-content" loading="eager" title="Pipe testing at 麻豆影院 CIEST Program"></iframe> </div> </div> </div> </div> </div> <div class="ucb-article-text d-flex align-items-center" itemprop="articleBody"> </div> </div> </div> </div> <div class="ucb-article-content ucb-striped-content"> <div class="container"> <div class="paragraph paragraph--type--article-content paragraph--view-mode--default"> <div class="ucb-article-content-media ucb-article-content-media-above"> <div> <div class="paragraph paragraph--type--media paragraph--view-mode--default"> <div> <div class="field_media_oembed_video"><iframe src="/center/ciest/media/oembed?url=https%3A//www.youtube.com/watch%3Fv%3DCSmie9je52A&amp;max_width=516&amp;max_height=350&amp;hash=2pXgmkfFlqnzXA60wIaiWUa5oh3Z356Y5TOe6-Ncq94" width="516" height="290" class="media-oembed-content" loading="eager" title="CIEST-PS12-30 sec"></iframe> </div> </div> </div> </div> </div> <div class="ucb-article-text d-flex align-items-center" itemprop="articleBody"> </div> </div> </div> </div> <div>The first in a series of testing programs at CU 麻豆影院 CIEST&nbsp;investigating performance of critical lifeline systems under extreme loading conditions. </div> <h2> <div class="paragraph paragraph--type--ucb-related-articles-block paragraph--view-mode--default"> <div>Off</div> </div> </h2> <div>Traditional</div> <div>0</div> <div>On</div> <div>White</div> Fri, 27 Sep 2019 06:00:00 +0000 Anonymous 175 at /center/ciest
