Nonlinear dynamic behavior of simply-supported RC beams subjected to combined impact-blast loading

Numerical analysis of axially loaded RC columns subjected to the combination of impact and blast loads

With increasing terrorist attacks in recent years, many researchers paid special attention to investigate the responses and failure behaviors of reinforced concrete (RC) structures subjected to blast loads. Generally, RC structures would demonstrate brittle damages and localized spallation along with ductile failure modes due to high-rate actions of explosions. Hence, the vast majority of the studies in the literature focused on recognizing the damage mechanisms and the material behaviors of RC structures under high-rate blast loads. This paper aims to comprehensively review on existing analytical, numerical, and experimental studies in the literature investigating the loading mechanisms, dynamic responses and failure behaviors of various concrete structures subjected to blast loads. In addition, the sensitivity of the blast responses of RC structures to various structural- and loading-related parameters are reviewed based on the findings of previous studies.
