Improved analysis and design of structures to resist blast and impact loads

Abstract

This research develops improved Single-Degree-of-Freedom (SDOF) analytical models and practical design charts to predict the dynamic response of reinforced concrete (RC) structures against extreme impulsive loading. Incorporating membrane actions, stress wave propagation, and nonlinear resistance behaviors, these models offer enhanced predictive accuracy over traditional SDOF methods. Validated through experimental and numerical analyses, the research bridges the gap between high-fidelity modeling and simplified analysis, empowering engineers with accurate, efficient tools for designing impact-resistant RC structures.
