Performance assessment of seismically-designed steel moment-resisting structures against numerically-simulated blast wave propagation

The main goal of this research is the performance evaluation sampled moment-resisting steel structure against 3D simulated blast loading. In first stage present research, numerically wave verified by comparing with relevant renowned numerical and experimental previous researches. second stage, sensitivity blast-induced pressure to finite element mesh size surrounding air cube dimensions are investigated considering one-story building block real based on Computational Fluid Dynamics (CFD) using AUTODYN hydrocode. innovation optimum for results compared empirical relationships toward realistic simulation structures. Finally, in last performances two seismically-designed buildings 1 10 stories achieved time histories formulations, UFC 3-340-02 guideline, studied. To assess structural performance, modeled tool OpenSEES. Performance assessment structures reveals that formulation loading will lead underestimation response, especially lower scaled distance scenarios.
