Abstract |
This study evaluates the blast resistance performance of reinforced concrete columns by applying two assessment methods: ductility-based evaluation and residual strength-based evaluation. The primary design variables selected for analysis include the longitudinal reinforcement ratio, transverse reinforcement ratio, and axial load ratio, examining their impact on the columns’ blast resistance. Additionally, by comparing the outcomes of both evaluation methods, a significant inconsistency was observed, indicating the limitations of relying solely on a single assessment method for blast resistance evaluation. This inconsistency suggests the need for further research to develop more reliable solutions for assessing blast resistance.
