This study presents a preliminary experimental and analytical investigation into the effectiveness of newly developed hybridized basalt fiber-reinforced polymers e-glass (B-CHSM) jackets. Twenty-four RC specimens were fabricated, with variables including unconfined compressive strength number B-CHSM layers. The results demonstrated significant enhancements in strain, improvements up to 325% 322%, respectively, compared specimens. Specimens an 15.5 MPa achieved increase ultimate three-layer confinement. For low specimens, strain 135%, 218%, 322% observed 1-, 2-, 3-layer confinement, respectively. Low-strength strengthened confinement showed 30%, 22%, 88% higher than medium-strength 75%, 165% high-strength evaluated existing models for FRP strengthening, revealing their limitations accurately predicting performance B-CHSM-confined concrete. Consequently, regression-based expressions developed, achieving coefficients determination exceeding 0.80. These utilized idealize stress-strain curves, enabling precise representation concrete behavior. predicted curves closely matched results, confirming reliability proposed methodology.
