I- SECTION WITH FLANGE PLATE UNDER PATCH LOADING ( UNSTRENGTHENED MODEL ) trengthening using triangular or closed-shaped stiffeners has proved to increase flexural resistance of the overall beam by reducing the effect of lateral torsional buckling (Ibrahim et al., 2012 [1], Hassanein and Kharoob, 2013 [2], Shaat et al., 2022 [3], Matloub et al., 2023 & 2024 [4,5]. A parametric study is performed to investigate the effect of the S
