On Sunday \u00a010 November 2024, in Professor Khaled Shaker Hall, under the supervision of Prof.Dr. Ali Hussein Ali Al-Ahmed,<\/p>\n<p>The study aimed to introduces an experimental and numerical investigation about the effect of encasing Glass Fiber Reinforced Polymer H-section on the performance of simply supported composite beams subjected to static load conditions.<\/p>\n<p>The main goals are studying the efficiency of encasing an H-shape on a rectangular concrete beam that is reinforced longitudinally with glass fiber-reinforced polymer rebars and transversally with steel stirrups.<\/p>\n<p>This lead to encasing GFRP I-shape in reinforced concrete composite beams improved ultimate bearing capacity by 20% and decreased the maximum mid-deflection value by 9.8%. GFRP I-Section had a unique performance and superior advantages closely related during loading stages; it increased the ductility index and bending stiffness by 8.85% and 112%, respectively. Deflection computation resulted in a clear reduction ratio equal to 9.83% and 18.03% when used studs and C-channels bolted on the top surface of the GFRP beam, respectively. These values ranged about 21.3% and 26.3% when using C-channels on the two extreme surfaces, respectively. The interaction mechanism was engineered between the embedded GFRP and concrete and played a crucial role by using shear connectors on one surface with various techniques; it prevented the slippage failure on the beam. The recommending for future work include<\/p>\n<ul>\n<li>Studying the performance of GFRP reinforced concrete members under fire exposure.<\/li>\n<li>Observing the effects of high-strength concrete (HSC) subjected to impact loading on GFRP composite beams.<\/li>\n<li>Investigating the effect of openings presence of GFRP I-section on the behavior of this beam type subjected to dynamic and impact loads.<\/li>\n<li>Developing the numerical methodology represented in this dissertation in studying the response of the cases in the three recommendations above.<\/li>\n<\/ul>\n<p>After the scientific discussion by the members of the discussion committee and listening to the researcher\u2019s defense<\/p>\n<p>The evaluation of the thesis grants the researcher a doctorate in structural engineering.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_gallery interval=&#8221;3&#8243; images=&#8221;6975&#8243; img_size=&#8221;large&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] &nbsp; The University of Baghdad witnessed the public discussion of the doctoral student (Fahad Mohammed Abdulkarim) from the Department &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.coeng.uobaghdad.edu.iq\/?p=6974\"><i class=\"fa fa-angle-left\" aria-hidden=\"true\"><\/i><span>\u0627\u0644\u0645\u0632\u064a\u062f<\/span><\/a><\/p>\n","protected":false},"author":165,"featured_media":6976,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[35,31],"tags":[],"class_list":["post-6974","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-civil-engineering","category-thesis"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
