Ground floor reinforced concrete columns are vulnerable to blast loading of close by distance (i.e. less than 3 1/3 m/kg ). In this work, a 25-story commercial building was designed in lowseismic and high-seismic regions respectively to find the typical column dimensions and reinforcements. A finite element model was developed to simulate above mentioned blast loading scenarios and to evaluate effectiveness of FRP retrofit. The model was found to be adequate in capturing the trends of deformation and damages as expected and effectiveness of FRP in providing additional confinement. The qualitative results thus obtained are presented.Structures Congress 2020 Downloaded from ascelibrary.org by 44.224.250.200 on 07/16/20.
