This paper looks into the behavior of beams with openings in shear zone strengthening with Carbon Fiber<br>Reinforced Polymer (CFRP) sheets under static load. The experimental program included four simply supported beams,<br>one of them without openings, one with openings (unstrengtheing beam), and two with openings strengthening with CFRP<br>sheets. One of the beams was strengthening before a test and the other strengthened at 50% of the ultimate load. The<br>ultimate load capacity, load-deflection curves, and crack pattern were investigated. The test results found that specimens<br>strengthening with CFRP sheets surrounding the openings showed great enhancement in the ultimate load reach to 152.1%<br>for beam strengthening with CFRP as compared with unstrengthening beams with openings, and delayed the appearance<br>of cracks around the openings and diverted their path. Numerical modeling through the ABAQUS finite element program<br>was introduced. The experimental and numerical study was found to have a high agreement. Parametric studies with<br>different widths according to ratios 3.5%, 5%, and 6% which is (the area of the opening to the total area of the beam) were<br>investigated.<br>Keywords: Rc Beams, Openings in Shear Zone, Strengthening from outside, CFRP sheets, ABAQUS<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/repository.qu.edu.iq\/wp-content\/uploads\/sites\/31\/2024\/05\/Experimental-and-numerical-study-of-strengthening-RC.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"\u062a\u0636\u0645\u064a\u0646 Experimental-and-numerical-study-of-strengthening-RC.\"><\/object><a id=\"wp-block-file--media-87924299-1e2b-4320-9c98-9a958a1e8dd6\" href=\"https:\/\/repository.qu.edu.iq\/wp-content\/uploads\/sites\/31\/2024\/05\/Experimental-and-numerical-study-of-strengthening-RC.pdf\">Experimental-and-numerical-study-of-strengthening-RC<\/a><a href=\"https:\/\/repository.qu.edu.iq\/wp-content\/uploads\/sites\/31\/2024\/05\/Experimental-and-numerical-study-of-strengthening-RC.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-87924299-1e2b-4320-9c98-9a958a1e8dd6\">\u062a\u0646\u0632\u064a\u0644<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Rand M.
