Evaluation of RC Beam-Column Retrofitting Methods against Near-Field Blast Loading
AbstractThis study numerically evaluated the retrofitting of RC columns using different transverse rebar arrangements and retrofitting methods using European standard I-section profile (IPE) and fiber-reinforced polymer (FRP) coatings. The degree of deformation, failure pattern of the element, and r...

| description | AbstractThis study numerically evaluated the retrofitting of RC columns using different transverse rebar arrangements and retrofitting methods using European standard I-section profile (IPE) and fiber-reinforced polymer (FRP) coatings. The degree of deformation, failure pattern of the element, and residual axial strength of the RC columns after exposure to a blast were the performance criteria. Fifteen different models were evaluated to determine the effect of spacing and arrangement of rebars and the effect of FRP and IPE retrofitting. The results indicated that the RC element with transverse rebars with branches showed the least amount of deformation. Furthermore, the damage and deformation of the structure against blast loading decreased by 25% and 20%, respectively, when applying I-shaped profiles and RC columns with FRP coating. The residual capacity of the columns was highest in the models retrofitted with FRP and IPE. |
