This study studies seismic retrofitting of RC shear walls with externally linked aluminium tube polymers (CFRP). Three stages complete the research study. This method examined two eight-story CFRP-repaired RC shear walls. Excited walls were tested. The wall design was considered in NBC and CSA-A23.3–04. Throughout. The École polytechnique de Montréal's shake table simulated earthquakes to assess wall seismic resistance. Vibrations make the sixth panel more demanding and nonlinear. Panel six finished the tale. The earth's surface and twelfth-level walls were repaired and retested on a shaking table with varying ground motion excitation levels. Ground motion stirred the walls toward the end. Phase 2 involved the erection of three RC shear barriers. My college Structures Laboratory evaluated cyclic lateral stimulation panels. Evaluate the panel's performance. Two FRP panels and the control wall were tested. These panels were evaluated to determine the optimal method. All three ceiling tiles have code-designed parts, including the sixth-story stiffener panel. All building shear walls exceed construction criteria; hence, all wall panels have these features. These walls can handle the eight-story shear stresses. Continuous axial load, synchronized cyclic moment, and shear force were tested on the top panel. The panel could withstand all three forces. FRP retrofitting improved the wall panels' flexural and shear strengths. FRP retrofitting failed. Third, a computational macromodel simulated gripping and recycling wall panels under cyclic pressures. This simulation determined the longer-lasting wall panel type. Control wall panels were tested to discover whether they outperformed retrofitted ones. The two existing RC shear walls and three RC wall panels' FRP-retrofit schemes performed well and enhanced flexural strength, proving the retrofit's key aims. The quadratic numerical macromodel recreated monotonic and cyclic responses in wall panels under cyclic stresses. Nonlinear effects were accounted for using the nonlinear model.
