| Seismic assessment and retrofitting of existing non-engineered buildings in Afghanistan remain significant challenges. This study evaluates the effectiveness of Fiber Reinforced Polymer (FRP) in retrofitting of a typical infilled reinforced concrete (RC) frame residential building located in Kabul City, Afghanistan. The solid infill panels, as vulnerable non-structural elements, are selected as retrofitting members. A three-dimensional (3D) nonlinear finite element model of a building with four and a half story RC building with three bays of varying lengths in both directions was developed and analyzed using CSI Perform 3d software. The building is studied in three different models: bare RC frames, infilled RC frames, and retrofitted infilled RC frames. Considering the materials and elements nonlinearity, therefore nonlinear dynamic time history analysis is performed. The analysis revealed that the soft story mechanism is applicable, primarily due to extensive damage at the first floor’s infill walls and columns fiber hinges. Therefore, the FRP laminates arranged as diagonal patterns on the selected infill walls. The retrofitting significantly improved the lateral strength and stiffness of the building’s model, thus the failure mechanism is controlled. Moreover, the interstory drift ratio of the model reduced substantially from 2.36% to 0.6% and from 3.2% to 0.8% in the x and y directions, respectively. As a result, the building’s retrofitted model gained sufficient resistance to stand well under extreme seismic ground motions. The findings underline the potential of FRP as an effective retrofitting method for vulnerable RC frame buildings in seismically active regions. | ||
